yes the math videos from 2006 IS REALLY HELPING
I hate that commercial
that ad just popped up for me lol. i was ticked off by it too and its not bc an ad popped up in the middle of my 2017 video grr
Jeysreee C 😂
Stupid ad i hate it
THIS COMMENT
the only YT channel that has been saving my ass since high school all the way to college
Congrats my friend
Damn can they make a simpler way to go about solving this bullshit. I done killed about 500 trees just to solve 2 damn equations. They need to figure something else out.
🤣💯
"What did it cost?"
500 trees and my fucking sanity, Gamora
LMAO!...now that's funny.
Yeah, good point about how much paper gets used up on this math! I think I'll try a dry erase board.
You just single handedly taught me more math in 18 minutes than I learned in half a semester of my math class. I love you.
Rizz class 🗿
(Joke)
THANK YOU SO MUCH. Math has been absolutely destroying me even though I have never worked so hard in school in my whole life. Thank you.
Dude thank you. Whenever I ask for help my math teacher always says “you should’ve paid attention” or “I already taught this”
I had teachers like that. Impossible to learn from someone who thinks you should totally understand everything the first time it was explained.
same
you're out here saving lives,thank you kind sir.
I want this guy to be my math teacher since teachers tend to NOT ERASE EVERYTHING ON THE WHITE BORED but this dude erased what he didn’t crop at 8:37 and I love that 💯
You are an excellent teacher and I thank you for this presentation. I'm happy you didn't end at about 45 minutes when you said you were done, that's when things got really interesting. Your clarification of when to use the absolute value sign on the variable was so clear and concise. This was exactly what I was looking for and I am very grateful to you.
My math teacher was absent and the sub doesn't explain it in a way I can understand. I was the only one who will finish the test today, but my math teacher left these videos! You're a life saver! 😭
i am 22 years old. Preparing to enroll into online college classes your videos have provided with so much information then before. I genuinely feel more confident and brave enough to solve any mathematical which comes my way. You are doing a terrific job teaching these stuff. Very huge round of applause
Great video, I'm Italian and I'm studying electronics at 47 and I have to review the equations and your videos are exceptional.
Thanks so much.
Best of the Best mentor!!! You know exactly what student want and you know how to present it!!! Stay Blessed!
You have safe me a lot i was weak at maths becus of you my maths has improve from zero to 50%. May God richly bless you for sharing you knowledge with us.
If I had this guy teaching math and science to me from 14 on, NASA here I would have come. Thank you.
Thanks, I have Test tommorow.😃
MR. Organic Chemistry Tutor, thank you for another awesome video/lecture on Solving Radical Equations With Square/Cube Roots, Two Radicals, Fractions and Radicals Exponents in Algebra. These Algebraic topics will only improve Mathematical and Analytical skills for students/non-students world wide.
Bro my math teacher legit just solves it in her head writes it on the white board and then erases it 2 seconds later. You are such a big help bro, keep it up.
man i am so grateful for ur work keep going bro u dont know how that saves millions of students
god freaking hell, why can't my math teacher be this guy!
I have online School and you have just saved me from a zero THANK YOU!
People say middle school is a nightmare
HEELL NAAH IT’S NOT WITH THIS CHANNEL!!
ain't no way you're seeing this is middle school
thank you so much dude! i was really not understanding in class but you made it so easy, now hopefully i remember this for tomorrows quiz xD
You're welcome
My grades have been dropping since I started taking algebra thanks for the help u are more helpful than a normal teacher
You're literally the reason my GPA is what it is.
This is the easiest way to understand it,and more clearly,Thanks!!
This channel has really saved my ass
truuu
10:40 a square root can have 2 answers on that case -2.5 or 2.5
No, that's only when you take the square root on both sides of the equation, that equation already had the square root so its not plus and minus. Same reasoning the square root of 25 is just 5, not 5 and -5.
i love this.. he took some hard maths question..
This guy is a hero
Do you only check to see if the solutions work if there are two solutions or should you do it every time?
For example: Would I check with just the solution x=9? Or would I check if it was a quadratic and there were two zeroes found?
I know I am not the person that made this video, however if it helps, I believe I have an answer! My teacher told me that you must always check the answers you get (whether it is two solutions or not). I am not sure if my teacher was wrong, but either way checking your answers is a good idea! ^^
I hope this helped!!
Thanks man! You really helped me out for my test!
The example at 2:50 actually has two solutions: X = 6 and X = -2
Well ,,done,,excellent,,I watched a few,,,but I only give you an excellent,,,you know why ? Because you started with very simple problem,,,
2021 and this is my go to math helper
should I always plug in the solutions in the equation to make sure that the soultions satisfy the equation?
It's not a bad idea. I usually check whenever I have at least two solutions.
yo this entire channel is literally saving my career+life. I wish I was joking lol
I will let you guys know if I passed my radical equations quiz lol. I'm very ass at math wish me luck
I got a 60 time to go committe suicide
@@fuzionxdoctor3576 don't do it stop and that's actually pretty good keep trying hard
@@Brianbravo2000 how is a 60 good lmao
gang meat it’s still passing dipshit
Roy Mane 65 is passing
you and sal with your different colored writing and black background are going to carry me to 1400+ on the Sat.
Always an awesome lesson. When I get a job, I will buy your hoodie.
for the equation of sqrt(x+1) = 2x-13. Before you do anything else, you must condition it x+1 >= 0 and 2x-13 >=0 therefore solution must be greater than 13/2 = 7.5. once you get solution, you can immediately drop x=5.25 out, keep x=8
can you explain a bit more on how you did the condition x+1>=0 and 2x-13=0 so that i can understand everything else.
thx
I wanna know how he got the -13 there
thank you very much for the help
14.57 should be sq.rt. of x shd be taken as denominator and solve left hand side and you get 9/6 which becomes 3/2=6 sort. x
Divide both side by 6 and you get 1/4=sq.rt.x so the answer is 1/16.
thank you so much
Thank you for this video , it really help me !!!!
Thanks for this video .that is very helpful for us
Thanks 🌾😇 i have a test in 3 days
I have a test tomorrow all about radicals, wish me luck 🙏
Let me know how you did :)
So?
Y’all my algebra eoc is tomorrow 👺 wish me luckk
What’s the equivalent definition of “Conjugate surds” in America Curriculum?
I needed this. Thank you!
Haha my favorite online teacher
i love you so much. thank you for exist in this world
This saved me
If there is no number next to the equal sign do we say it is equal to zero? Or do we just square it and say its square is equal to a square?
Thank you man
thank you this is really helpful
IN THE FIRST 2 EXAMPLE CAN YOU DO THE CHECKING?
very good method
3:45
In Blitzer I see this rule :
If X^(n/m)=A then, IF n IS EVEN, then, X= PLUS OR MINUS A^(m/n)
In the equation that is solved here, n=2, so n is even.
So
(1) (x-4)^2/3=4
(2) (cube root of x-4) ^2 =4
(3) cube root of x-4 = plus or minus (square root of 4)=plus or minus 2
(4) (cube root of x-4)^3 = ( plus or minus 2)^3 = plus or minus 8
(5) x-4=plus or minus 8
(6) x = 12 or x= -4
Is this correct?
Thank you man this helped a-lot .
we learn on youtube and on our spare time we go hang out with our classmates and teachers
thank you sir
What is the app u used
Math makes my head hurt 🤯
11:50 I think you still have to foil this even if it’s positive
1:08 x = 61
Thanks for this great video, but why do we need to foil in the third exercise? I dont get it. :(
It’s like doing 2 digit multiplication.
You multiply the ones and tens digit in one one number by the ones and tens digits it the other number
12^2 = 12*12 = (10+2)(10+2) = 100+20+20+4 = 144
The mistake that people make is like doing (10+2)^2 as 10^2+2^2=100+4=104 which as you know does not equal 144
3(2x-4)^2/3+5=17
The answers are x=6 and x=-2
7:22 negative 53 squared
what about tricky ones like ✓x² = x, you'd expect it to be x = x always true, but the result is x ≥ 0
(a+b)^2=(a-b)(a+b)
how would you solve this equations square root 2x - square root of x+1 = 1
Cynthia Alley you square both sides to remove the square root so you will be left with. 2x-x+1=1.
Now 2x-x=1-1
2x-x=x
1-1=0.
So x =0.
Fill in the answer in the original equation it will be 1=1
@@adamabdallah2604 hey question, can you actually square the sqrt of 2x - sqrt of x + 1 = 1
Because as far as I know you can't square two terms separated by plus sign or minus sign? (unless you're gonna foil it, which I think you didn't..?)
but what if it is like the square root of x plus 4 minus 3 equals 1how would i solve it with a low number?
The answer will be 0.
Not me in the bathroom during my final to learn how to do this last second
time stamp 4:53
شكرا
What if there's a square root on one side and a square on the other? Something like this; sqrt(x-5)=x^2+5. I've been trying this for a while and get no where.
Why is that the equation on 10:50 doesn't work? Can't the square root of 6.25 be -2.5? I thought normal radicals usually have both negative and positive roots? Isn't -2.5^2 the square root of 6.25 as well? X can be both 8 and 5.25.

I know this is an old video, but you didn't tell us WHY
we're raising the second equation to the 3rd power, rather than to the 2nd power...!
@2:14
Um because the operation has a cube root, it shows it right there on the left. There’s a root, and it’s to the third. Cube root.
So inorder to cancel the root, you need to multiply both sides by the power of three.
@@jin_cotl TY, I see that now.
I want to study online with you! Do you have online teaching tutorial sing in!!!!!!!!!!!!!!!!!!!!!
iu think u can check for him on study pug
4:42 this is what I’m looking for...
why dont you move the 5 to the other side instead of dividing it on both sides?
It’s the same thing just ignore it
Uh, which problem are you asking about? Can you link it?
It was very helpfull. Thanks for sharing 😊
You have to do this in organic chem?! I’m doing this in algebra 2 ugh
What is the purpose of this comment?
I know you see me what’s the purpose of yours
My brain left my soul and body at fourth
problem
fuck this quarantine sh*t i cant fricking learn by myself can it all end already, I thought I would never say this but i miss school :(
4:41
Can you answer this one?
Square root of (x-2)=square root of (x)-1
x=1
The square root of 6.25 is +-2.5, not just +2.5, which means 5.25 is not an extraneous solution. Just saying.
@John nope....nope you're not.
Yes but again he is only considering the principal root. So negatives are going to be avoided. And to actually check if the final answer works you have to substitute this to the x in the equations and this works.
Sir please solve this 60/5x =60/6x +12/60
I can solve it
60/5 x = 60/6 x + 12/60
12x = 10x + 12/60
LCD: 60
Multiply by everything by 60
(⁶⁰) 12x = (⁶⁰) 10x + (⁶⁰) 12/60
720x = 600x + 12
Move variable to left
720x - 600x = 12
120× = 12
Divide both sides by 120
× = ¹/¹⁰
LightlessFade thank you sir
My teacher said the answer was wrong even though i did it the exact same way 2:29
book mark 4:00
Put -32x-21x This is easier.
Wow...that’s great😉
thanks ♥
15.26 is not right please do it again.
How is 4+6 = to 8 and not 10
how come the 52 become 53 at 6:12 please tell me master
He got it from:-52-1 =-53
