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.
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
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.
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.
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.
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.
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!!
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
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?
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.
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! 😭
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.
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
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.
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..?)
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.
wasted 3 hours learning how to do these just to find out we arent doing equations in class, just simplifying individual numbers, like sqr root of 128 is 8 square root 2 smh

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.
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.

The example at 2:50 actually has two solutions: X = 6 and X = -2
god freaking hell, why can't my math teacher be this guy!
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.
My grades have been dropping since I started taking algebra thanks for the help u are more helpful than a normal teacher
This is the easiest way to understand it,and more clearly,Thanks!!

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
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.
Well ,,done,,excellent,,I watched a few,,,but I only give you an excellent,,,you know why ? Because you started with very simple problem,,,
You're literally the reason my GPA is what it is.
This guy is a hero
Man all your classes are really helpful thnaks a lot
i love this.. he took some hard maths question..
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
2021 and this is my go to math helper
Thanks man! You really helped me out for my test!
Y’all my algebra eoc is tomorrow 👺 wish me luckk
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?
This channel has really saved my ass

I will let you guys know if I passed my radical equations quiz lol. I'm very ass at math wish me luck

I have a test tomorrow all about radicals, wish me luck 🙏
Let me know how you did :)
So?
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

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

thank you sir
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.

10:57
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

It was very helpfull. Thanks for sharing 😊
10:37 shouldn't sqrt of 6.25 be ±2.5?
Meaning answer can be +2.5 or - 2.5
So ±2.5 = -2.5 is correct...? Or is it only half correct or what
My brain left my soul and body at fourth

what about tricky ones like ✓x² = x, you'd expect it to be x = x always true, but the result is x ≥ 0

x=1
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
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?
