Learn Algebra 1 and 2 in One Video
HTML-код
- Опубликовано: 25 июл 2024
- I show how to solve just about every type of problem you will ever see in both Algebra 1 and 2 in this video. There are numerous problems that I work out live on screen, while explaining all of the rules required to solve each problem.
This video was originally a Livestream so many people ask questions during its filming. I live code every Wednesday at 5PM UTC / Noon EST here / derekbanas
Next Wednesday I'll teach all the Trigonometry you need for Calculus on Twitch!

This man catapulted me into a 175k + Bonus/yr job in software development. Years later he's still helping people!
Congratulations on all that you have accomplished!!! I'm very happy that I could help :)
That's very inspiring :)
Here here! Derek and his video series helped alter the course of my life for the better as well. There should be an award for RUclips for people that make such a positive difference.
Funny you should say. I started watching his Python tutorials around 6 years ago. It radically improved my efficiency at work by writing a bot that basically automated about 60 percent of my job. My boss never did know how I did my job much faster than my coworkers. Then I got a job doing similar work for about twice the pay based on those skills.
Im looking into software development too! Thanks for the motivation! 😊
Thank you Derek! I was preparating myself for aerospace engineering (even though I still have a long way to university). I made a playlist with some videos to help me preparate myself, and made it public, just so you know. Thank you a lot to let me learn all this content!
Beautiful! I've got my International Advanced Level (IAL) exam this year's May/June and your videos are helping me a lot. Looking forward to linear algebra and calculus videos!
As a self-taught Software Engineer - been at it for 10 years professionally now, and I am admittingly lacking in the Math Department. My journey began at learning Calculus, which quickly led me to realizing that I am not strong in Algebra. Long story short - I was looking for some no-nonsense, but very thorough, learning resources, and I can say that this series was all I needed other than just pure practice.
Btw I am working my way towards Machine Learning, and I can also attest to the fact that ML is ALL math. If you don't know Algebra... you're not going to be learning ML :)
Cheers!

The best channel that will definitely feed the hunger for knowledge.
Thank you for the nice compliment :)
Lol 😂 same here. I struggle with it now I can understand it better.
Ooh exactly legit fr irl imho @op. That is one of if not my favourite things about yt is it is like the internet fwiw ftw evne., full an fileld with so much abundance of learning/teaching video of many skills and a vast array of knowledge among the plethora of music videos/ytp's etc. That is ftw fr.
My fav yt channels I feel teach me somewat in some way or another.
Or that at least I can and have a desire for learning something fwiw I can take away from each video now.

Hi Derk, Thanks for the math brush up, needed it to help out my kids. I follow your channel from 2008, amazing the amount of knowledge you poses. Keep it up mate.
Thank you very much :) I’m happy the video has helped with your kids. I help my kids with their homework as well every night
Thank you so much this has been extremely helpful!
Simple mistake at 5:55, but I'd like to address it: multiplying x by x gives you x^2. You would only get 2x if you combined like terms such as x + x. Other than that, great video! Very helpful!
What a dumb mistake! Sorry about that. I'd edit it out, but there was no easy way
ruclips.net/video/y2yo6MRm_Zc/видео.html
Looking forward to calculus 1 and 2. Thanks again for the video
This video probably just saved me for Algebra 2, so grateful that I could review all of the basics.
Thanks for this great video. Will be good to refresh my brain with these concepts.
I’m very happy you liked it :)
You are one awesome person, you’re channel brings so much value. Thank you ❤️
Thank you for taking the time to write such a nice message :) I appreciate it

These are some of the most helpful math vids ever
Insightful and makes me think and have fun
Dude you are awsome for this!!!
This helped so much! TYSM 🤪
This is a great video to remember all the skills I had previously forgotten.
this is super helpful for recapping, i haven't done algebra in a while
I'm very happy so many people are finding it useful :)
Its been many years for me.
Hello, great work! At 34.00 minutes of the video, - 2
retaking the act next tuesday and i rlly need a refresher on algebra
❤smart
Just took my first universty course in linear algebra, i figured out i had some problems with basic algebra. Amazing Refresh. Thanks alot from Israel !
wow man , this is the best revision of basics i could possibly hope for, +1 subcribeD :D
Thank you very much :)
Thank you this is really helpful.
this Video is the reason I was able to pass Algebra, I struggle with Maths I lot and this helped me so much, thanks
That's awesome! I'm happy I could help
Helped me pass my algebra midterm and now will help me pass my regents
this is a litteral life saver i have a HL math final tommorow and im tryna cram evrything in as much as possible
thank you! can’t wait for the calculus video
….
I cheated the whole year in algebra 1 and didn’t learn anything and now there’s a placement test coming up that I can’t fail
still need to work on my basics. wow. I got lot of climbing to do if im to follow this. im ready for the challenge... LETS GO!
Mistake at about 5:52 .... x times x isn't 2x is't x^2 ... at 1:10:10 your second step is technically not equal to the starting problem as he suggests it is, so even though he gets the correct final answer it's confusing....at 1:15:30 the second rule is wrong, the 2 should be an a..... at 1:32:25 he says 2 and 6 work and then proceeds to write a 2 and an 8, so it should be (x+2)(x+6).... I see now at 1:34:45 he corrected that last one after someone commented..... at 1:37:20 he says 2^2 when he meant to say 2^3. However he fixes it in the next step and gets the right answer...... at 1:39:00 he says (x-3x) when he meant (x-3)... then he gets the final answer wrong as he uses (x-3x) again... which is obviously wrong as it simplifies to -2x but he's clearly trying to get this done as fast as possible and not catching these things... and I think fatigue is setting in lol..... 2:16:40 I think this explanation of what makes the function even or odd is pretty confusing, especially since you said -x^2+2 is equal to (-x)^2+2.... this actually isn't true because in the first one only the x is squared but in the 2nd one the square is applied to the negative sign.... he makes a similar mistake in his explanation for the odd function that follows...and to say substitute a-x for your function isn't really helpful... didn't even explain what a is...honestly I didn't understand that sentence at all... I think maybe he meant to say that f(x) = f(-x) which would be the true definition of what makes a function even...but then he did say that shortly after.
hello there, you seem to know what you're talking about so i was just wondering at 56:54 (finished problem) i know that he shouldn't have dropped the negative from the 3 at the beginning, but how did he get l x + 2 l = -2 from 3 l x + 2 l = -6? i have no clue how 4 was just suddenly added to the equation. do you think you could just work me through the entire problem?
Actually after looking it over again, I realized that he did it correctly and removed that part of my comment.... he still didn't explain it very well as he hasn't in a lot of this video as he's just trying to go through everything really fast and so he isn't covering a lot of the details..... but let me re-write his steps adding one more in the middle to help explain how he got his final answer:
9-3lx+2l = 15
-3lx+2l =6 (after subtracting 9 from both sides.... he did this step and the next one in one step)
3lx+2l = -6 (he divided each side by -1... he just saw that there was a negative sign that he'd prefer on the other side so he intuitively moved it to the other side... I wouldn't have done it this way but nothing wrong with it)
lx+2l =-2 (he divided by 3 on both sides)
From here you can see it's no solution.... of matter what you plug in for x, lx+2l can't equal a negative number... x+2 could be positive or negative but either way lx+2l can't be negative.... I don't know why he wrote x+2=-2 at the end.... it looks like he was starting to go through the next step that you would take if it was an abosolute value problem with a solution but then realized that it wasn't nesasarry and just stopped.
@@Josh-zt8dw wow thanks so much! appreciate it!
an awesome resource for high school and college students. highly recommended
Thank you very much :) It is fun to take on these challenges
Algebra 2 summer school highschool course is kicking my ass. If this video doesnt work honestly i give up.
Thank you for this video...
One of the best video for mathematics... Totally high school basic but thoroughly explained... Please ping here your machine learning playlist.. unable to find..
Variables and some of the operators are used in programming! I’ve also seen people solve algebra problems with JavaScript
Great content. Thanks for sharing.
Thank you very much :)
You're awesome!
Great video.
Hello, first of all thanks for the video. Could anyone tell me why the inequality was not fliped at 34:11 thanks alot.
Hi again mate, i already follow your "learn algebra" series, should i watch this video after I finish the series? or are these the same lessons?
These are not the same lessons, but it is way more intense and fast. I recommend following the slower multipart version
God bless you, sir!
God bless you and your loved ones as well :)
It's 4am, i'm high af and last time i learned basic algebra was 6-7 years ago
ruclips.net/video/y2yo6MRm_Zc/видео.html
Good day, Derek!🙏
Thank you :) I hope you have a good day as well
Hello, I just have a question about 23:49 and if b = 1/4 or is added for 7/4 as when I attempted it it seemed liked -3/4 I am just reviewing for a new algebra two course I’m take but your videos are super helpful
Thanks for much for this video
I'm a junior developer and just finished your algebra video
What other videos or topics are there that would be most beneficial to my in your opinion ?
If you want to into Machine Leaning or Data scence then Trig, Pre calculus, calculus, linear algebra.
i like all of your videos
Thanks
Have you ever thought about doing shader programming here?
I’m planning to major in astrophysics so I definitely need to master math and science thanks for posting
how fast and efficiently you taught this was wild i completed the whole thing from scratch in 3 days lol.
hey guy, what do you think, this tutorial is enough to study about algebra 1 and 2, so can we now practice this more and move forward
Self teaching math with this one
Dude, I think you've saved my sophomore year.
Happy to help :)
What video do you teach the other algebra term?
your the best thank you
Thank you for taking the time to write that message :) I appreciate it!
24:08
I am little bit confused. Shouldn’t the y-intercept be -1/4 or am I missing something?
I worked out the problem and I don't see how you are getting b to equal 7/3 at minute mark 23:32. Can you explain in a little more detail? Thank you
Do you have a course that teaches Calculus? You have so many videos.
hi mate
i hope this will lead me to basic calculus and to advance calculus
I want to learn more about calculus. I am still learning new things about pre - calculus
I’ll be covering calculus at some point this month
At minute 24, where did you get 3/4 from?
Hello Sir Derek,
May I ask for your advice?
I'm having hard time learning frameworks. I tried learning flask, django, and currently laravel.
I gave up on flask and django because I find them extremely difficult.
Programming using these frameworks feels like I'm tied into a chair. I feel restricted and no freedom is given.
Things such as classes, methods, requests, etc. are supposed to go into specific locations, and I find it difficult to memorize all of them.
Have you experience these before? If so, how did you overcome it?
Thank you.
Learn from Durga Sir..He is God of Python....You will understand everything,,,just search on RUclips:--Django by Durga sir
What app do u suggest to write on iPad like you do
I love this guy
Thank you very much :)
Hi Derek how do you record your videos on iPad? thanks
I stream the screen using AirServer on Windows to OBS
Can we have a link to your ML course?
34:11 you forgot to flip the > when multiply by minus so its x < 6 and not x > 6 it was easier to just leave the 2 in his place and move the -1/3 to the other side
Thank you so much. I am taking an electrical engineering career training high school class. The prerequisite is a minimum of a c in algebra. I was never good at algebra. This should hopefully help.
I'm happy I could help. This is basically one example for most anything you'll ever see in Algebra 1 and 2. If you can solve them on your own after watching this you'll get an A on every algebra test
@@derekbanas So if I can Solve the Algebra 2 Questions on my own after watching this, I'll be alright during tests? I'm a Sophomore in highschool taking it and I am really struggling with this. So if I do the problems by myself I'll pretty much know like 80% of Algebra 2?
Education is strong!
You know it!
What program did you use for the blackboard?
He says He is using Good notes
watching this 10 hours before my SAT💪🏽
at 1:56 why are we multiplying by -6? I thought what was missing to make the denominator would be 6(x-3) I don't understand the -6(x-3)? Can anyone help
Hello Mr. Banas, I hope this message finds you well. As a senior in high school preparing to start college this fall, I am planning to take college algebra and I was wondering if you know of any additional resources or tips that could help me prepare for the course. Thank you for the video!
I think two resources may help. The No-Nonsense Algebra books are good. I'd use them in combination with an app like Symbolab. Symbolab will take a picture of any problem and then explain step-by-step how to solve it. There are only so many different types of Algebra problems you will ever see. If you set them up and can solve all of the types you can solve them all. I did my best to provide one of any type in this video, but additional resources and problems always help.
@@derekbanastysm!
5:52 typo, should be x^2
9yo me learning this: 👁 👁
💧👄💧
I've heard the word coefficient so many times and yet only just learned what it is 😹
I'm happy I could help :) I teach what a lot of big words mean in this video
Hey, Derek... Which regional dialect or accent you speak with?
why did the slope go from 10/-3 to -10/3 at 18:40. I don't understand is this part of the formula or did he just move the negative, I am very confused?
Hi everyone, may someone explain to me whether I'm right or wrong if I get an answer of x=4 and y=0.25 for the question at 38:59
@ 1 hour and 18 minutes roughly,
Factoring Trimials:
X^2 + 8x +12 = (x + 2) (x + 6)
You wrote:
(X + 2)(x + 8)
Sorry about the typo. I correct it a little later into the video
Can't seem to access the download notes.
I just checked and it works bit.ly/AllTheAlgebra
Geometry,Calculus,Economics please !
Trig for Calculus is coming this Thursday on Twitch and next Thursday on RUclips. Then I'll move on to Calculus
and Finance and maybe accounting.
I'm confused, at 23:32, you claim that we must set x = 0 to easily find the y intercept.
That's not how I did it. I would substitute "y = mx + b" with the values in the given point and the slope that we had found. It gives the same answer, being 1.75, but I don't get how you did it.
my god i am learing python from you sir on udemy
At 5:55, I think you said that x times x is 2x -- shouldn't it be x squared?
I'm a grown man, probably old enough to be someone's grampa.
Even kid's algebra is a much needed refresher..
what... a.... hero..... top guy
Thank you for taking the time to write such a nice message :)
@@derekbanas Derek, are you going to do a complete course on Calculus? thank in advance and keep up the wonderful work. I am a big fan of what you do!
Derek Banas at 12:59 isn’t the answer suppose to be -3?
2:05:00
I'm confused where b = (4/4) + (3/4) = (7/4) came from at 24:01. Can anyone explain? When I solved it I got y = (1/4)x - (1/4).
Since he was going so fast, he didn't repeat that the original question was to find a line *parallel* to x - 4y = 1 that intersects a point of (-3, 1). That means he had to, first, find "m", the slope of his line, which will be the same for the parallel line, and then find "b", the offset up or down the y-axis for the parallel line. So with y = (1/4)x - 1/4, he had solved for "m", and then he could solve for "b" by plugging in his known values into y = mx + b. So taking y = mx + b, knowing that the slope is 1/4, and this parallel line intersects (-3 ,1), you would start with 1 = (1/4)(-3) + b. Now, he skipped a few steps with writing this out and instead just started with b = (4/4) + (3/4), to get b = 7/4, which without referring back to the original question, looks and sounds confusing, but it means the parallel line is y = 1/4x + 7/4. I think he zipped just a little too fast there. This is a crash course mostly for people just refreshing themselves, but teachers should avoid doing steps in their heads while instructing.
@@ExterminatorElite This is the MVP comment right here
@@ExterminatorElite Thank you very much !
al gebra 3 pls
So if i do this course can i do your machine learning course or do I need more advanced math? Im confused
You should be fine. I don't use much math aside from linear algebra and when I do I explain everything
@@derekbanas Awesome will the algebra course suffice ? Do you explain statistics topics like linear regression I would love to know.
Check that so do you recommend after this algebra video, i take your linear algebra course and then ML? Or jut this algebra course and then ML? @@derekbanas
23:51 where do you pull the numbers for b? I was following along up until that point. Are you using the initial eq x-4y=1? Rewritten to -4y=-x+1 -> y= 1/4x -1/4 which is y= mx+b for that and then the new eq at least so far is y= 1/4x + b. My thoughts are kinda scattered so this is probably not being worded too properly I’m just trying to see where the 4/4+3/4 = 7/4 comes from
Okay I think the process of point slope form was just skipped? Y-y1 = m(x-x1)
Y-1 = 1/4(x-(-3))
Y-1 = 1/4x + 3/4
Y = 1/4x + 3/4 + 1
Y = 1/4x + 3/4 + 4/4
Y = 1/4x + 3/4 + 4/4
Y = 1/4x + 7/4
Goodmorning, it seems you tend to knoe this stuff. Can I ask how to solve that particular equation from the start? I'm sorry I think I did get a bit lost after he start changing the position of -4y and the equal signs and things just went move on and on and I don't know anymore. Thank you.
