Algebra 2 - Radical Equations
HTML-код
- Опубликовано: 25 фев 2013
- Here we tackle radical equations involving multiple powers. Notice the Maryland basketball jersey... gotta give props to home! Another fancy way to describe this topic is square root equations. Check out the unconventional way we ended this lesson... YAY MATH!

I'm actually loving this classroom. Everyone has such a good attitude and students aren't afraid to participate. Good work, my friend
So True
Yep
Even though I've never met you, you are the best math teacher I've ever had.
Why the fuck do i pay for college? This man accomplished what my teacher failed to do in an hour of teaching...in less than 25 minutes!!
Thanks so much. I'm in the 11th grade and I'm taking Algebra 2/ Pre-Calculus and this was sooo helpful. You and your class explain things very clearly to me rather than my teacher.
And gooo Maryland. I was born there too
+Shalaine McCall is Maryland a state?
This man be saving my math grade
+Aaron Tyrie LMFAOOOO
SAME! Lol my teacher sucks ass at teaching. She doesn't even teach! she just makes us watch videos and read the textbook. TF
Aaron Tyrie ikr
Aaron Tyrie SAME
lol my teacher gets mad at us for asking questions and then afterwards he's like "WHY DON'T YOU GUYS UNDERSTAND ANYTHING!!!"
I'm glad that math teachers are utilizing RUclips more productively. My math teacher isn't that bad, but I still can't understand her lectures at the end of the day, and I spend hours upon hours doing math homework at tutoring.
I've been struggling w/ radical equations for 2 weeks now. Took me just one watch of 2 of his videos and I completely understand now. Wish my teachers were as entertaining as you!
"He's not the hero we asked for but he's the hero we needed." - Every college & high school student ever
This guy is SO GOOD AT TEACHING!!! He basically taught me better in less then 30 minutes than my teacher did 1 hour and 30 minutes. I WISH HE WAS MY TEACHER!!!!
I wish I was in your class, everyone seems like they are participating and not afraid to ask questions
I had a chemistry teacher in high school who was amazing. He made hard stuff logical and digestible for everyone. You are even better. YAY for yaymath!!!!!!!!!!!
"yaymath" and "mathbff" are by far the best Math tutorial videos are RUclips.
👍
wish I knew about him and his site when I was in school. He is AMAZING with Math
you explained it better than my teacher, good job sir.
Before the video I got an ad asking me if I'm tired trying to find help for math on RUclips XD
Dr. Insanity lol
Dr. Insanity yeah everyone gets that ad
he's there for my math grade when nobody else wasn't
You might want someone for your English grade
rae531 I love your avi! The 100 is one of my favorite shows on Netflix!
Tommy Flynn lmfao u right
Tommy Flynn good one
I wish I had this guy as a teacher
i like this guy! makes it fun...wish my prof. was like him...
Sincerely appreciate how you treat your students. You're wonderful man!!
I respect this teacher so much so enthusiastic thank you for doing a double radical equation
Thank you sooo much! I totally needed this after missing school for a whole week and missing this lesson. Bless your soul!!!
can you be my teacher please? mine sucks
mina marissa
I loved math because of my high school math teacher. actually, it is my favorite subject. And when I saw your videos I noticed that you remind me of my teacher a lot. That's why students and viewers love you and your classes. I'm lucky to have that teacher in high school or I will end up hating math my entire life lol. and we are lucky to have you here to save our lives.
am havin a nightmar of solving this probe, (2-3) rise to power 2, cos am preparing for an exam this year. thank u teachers for inspiring us. God bless u guys. cheers and HAPPY NEW YEAR.
Thank you so much! You are my new go to math teacher, since mine doesn't get through to me at all! I also love all the effort you put in to get your students to have fun while learning! :)
im 36, love math, its been a while and this problem came up on facebook i couldnt get and pist me off lol i needed to comeback and retrain my brain. my kids to young for algerbra, trig or calc in school so came to RUclips, thanks for video
Love the way you teach ! better than my professor in college ! thank you !
I love this man and his students. I was wondering, is there the next part of the video, dealing with radical inequalities?
Also the fact that the kid said "pass" and the teacher said "totally fine" shows that he is truly a fantastic teacher. He is treating his kids with respect.
I love this guy!! He is amazing at explaining concepts. These kids are so very lucky to have him. Thank you for all the videos. I was cracking up at the "information overload!"
this guy is a genius helping me out right now thank you SIR!
no way, the third question is on my hw, better yet, THATS WHAT I NEEDED HELP ON TOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
YAY MATH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! THANKS MR.Adhoot
Omg I have been studying for my math midterm for days and I couldnt just learn to solve these problems till I got the brilliant idea to use RUclips because i learn visually you know and snooping around I found your page! You are my life saver! I finally got it!
Thank you for your videos. My daughter needs this.
you are like the best teacher ever i actually listen
@ 20:11 X = 2 also works! The square root of 2 + 2 is the square root of 4. The square root of 4 is 2. 2 squared = 4. 2 - 4 = -2 Negative 2 squared = -2 * -2 which = 4. 4 = 4.
I see your point but remember the original equation which was Square root of x+2 equals x - 4. If you plug 2 into it you will get square root of 2 + 2 which is 4 and then square root of 4 is 2 and on the right side you get 2 - 4 which is -2.
You don't square both parts because that's the method we used to solve the equation but that doesn't belong to the equation, per se.
I wish I was in this math class. He seems like such a fun teacher.
"Are those videos from 2006 really helping"? Damn.
hahah
same
Very clear and concise. Yay for YAYMATH!!
I've looked through a lot of vids but this one explained it best
After seeing this, i know for a fact that my math teacher should be fired. IMA GO DO THAT
at the 13 mins and 45 secs in this video, why did you divide by -6 in both sides? aren`t we supposed to divid both sides by +6 since -6 was already there? PLEASE REPOND THIS CONFUSION, I WILL BE WAITING...
you are an awesome teacher and thank you for being so great with kids.
Subscribed!
I've stumbled across this channel a few times this semester. These are REALLY good videos man!!! Good Work
I like ur video it makes my maths knowledge better and my marks too. thanks.
You are awesome. I watched so many vids. right away I got it watching yours. Thanks! and forget those haters.
Hi Morgan! Thanks so much for the message and what a story. Perhaps you can inquire whether your school arranges for guest speakers and I can come visit. Let me know, I'd be honored to be there.
You are the most most "radical" ^2 EVER!!! Love YAYMATH
Best math teacher i never had...
thank you! my teacher spent two hours explaining this to my class, but it made no sense. your video made everything simple and clear! thank you thank you thank you!
these students are lucky to have you as a teacher. . .
The first solo was fire
OMG you just explained everything my math teacher took two hours making it all complicated and boring, in just 25 minutes. Thank you! :D
Omg thank you soo much! I'm having my Math final exam tomorrow and this lesson was the only thing I couldn't get! thank you you saved my marks😀
this video helped a lot! wish my teacher were like this, mine laughs at us whenever we ask questions.
Lol mine too he enjoys seeing us suffer T^T
Enjoying your videos. For problem 3, wouldn't -1 also be a possible answer to the square root of x-15 (and therefore x=16 could be a solution)?
Anyone else think this guy reminds you of Ezra from PLL???
ALicia c STOP 😂
YESSSSSS I THOUGHT THAT TOO. I'm totally aria in this situation
@Aliciac
ALicia c
You are a math angel!!
Best math teacher ever
Im moving to California to be his student
Thus was SOOO much help and you are an awesome teacher
It took me quite a bit to buy the fact that that one radical equation had NO solution. So to convince myself I had to take each member and make y-functions out of them and then proceeded to graph. Seeing that the graphs could not intersect...then that was when I was convinced.
I wish I had this class!!
this video helps me a lot compare to my teacher in school.. Thank you sir ^_^ i really appreciate your teaching methods ^_^
the best teacher of mathematics i seen before 👍❤️ keep going up 💪
a + √(2x² - 3) = b
Can you substitute the given values for a and b to see whether they result in the square-root expression being set equal to a negative number. I'm having trouble with this problem.
this dood is highing my math grades
Shouldn't 2 work also (second to last problem)? I keep plugging it in and it works. Thank you.
Thanks! Very Helpful!
Omg!! Thank you yaya math!!!!! You rock!!!!!
No Sean, if you plug in 2 for x then it will be 2+1=3 and then you have to square 3 (i don't hav a calculator) so the square root of 3+2 will not equal 4
Your the best.😀 When I dont get a chapter or lesson😭. I come to you😎. And all the questions 🙋I have, your wonderful student's ends up asking🙈 them. 🙉 you guys subscribe to this channel🎥😃 im telling you.. His the best !😁
"I'm glad you know your colors"
Well he's not the art teacher is he?
Why do you only take the positive square root of a number? Shouldn’t be there a plus or minus sign?
Thank you sir, you are a fine educator!
Can anyone explain what happens to the -9 at 18:50 to me ? thank you
you, n your classmates make math so much fun,,,yay math, owww!
Great. Interesting class...
Such a cool teacher.
square root of 1 could either be 1 or -1 so the answer for the problem in 8:33 is 16
super helpful. thanks
Yo! I really got through my math classes with this guy! lol
I love your channel each of your videos blow my mind I mean I understand it but it just blows my mind how it works out. When I first look at it im like holy shit! Now after I saw you work it out im thinking this isn't so bad kinda fun.
ok so on 6:40 how would you find out that it was five? I understand the -5 time -5 times -5 is -125 but if it was a different number finding its cube root may not be that easy. Is there a way to find the cube root of a number?
Man! Gracias! This helps a lot!
This guy was amazing
I love you dude you always got my back!
you're a good teacher man. I watched some of your other videos too
Pretty animated class!!
So helpful!
Thank so much !
Amazing teacher!
I wish this dude was my math teacher
The first test is confusing, because when x = 3 (final answer) it will mean that 1.73205 + 1 + 2 = 4 And that simply doesn't add up. Where did I make the error?
+Bezwaar IkTeken the 1 is inside the radical, so its sqrt(x+1) = sqrt(3+1) = sqrt(4) = 2+2=4
Estimate negative cube number
FLVS algebra 2 honors and I'm just coming out of my freshman year... yikes
Not as bad though, I feel for the AP calc kids
wish my teacher was this fun XD
GOOD VIDEO...THANKYOU
So for the last problem idk if I'm right but does x=10.5???
