Solving a Radical Equation Using Factoring and Checking Your Answers

👉 Learn how to solve radical (square root) equations having one radical term. To solve a radical (square root) equation having one radical terms, we isolate the radical term by placing it in one side of the equation. Next, we get rid of the radical by taking the square of both sides of the equation and then solve and simplify the resulting equation.

I learned and understood what Im supposed to do in the first minute of the video compared to what my teacher taught us in a week

[shapeshifter]

when he writes on the board it’s so satisfying

[raina]

Whose else is last minute studying watching all his yt vids

[levismith]

For Christ's sake Justin! Pay attention!

[roxy]

Covid got me watching this, thanks teacher

[mohammadmeelad]

Thanks







Why do you hate Justin?

[CyberMedic]

I really like these short, straight-to-the-point videos

[wesfisher]

This is my friend Justin, he’s already taken.

[bsc]

Thanks you for fast and easy explanations wish u were my teacher and didn’t have my robot talking one that I have trouble learning with

[jenroberts]

Awesome! Thank you for being clear and concise!

[bellpebber]

He said, "you still with me" right when I was dozing off to sleep deprivation, thanks for your videos!

[codytullock]

Pay attention Justin! come on how many times do we have to go over this!

[SpaceSucc]

How do you determine the domain of these? My teacher went over it fast but it didn't make much sense. i.e √x-2

[touhami]

Sqrt(A)=B is equivalent to
B>=0 and A=B^2

Here sqrt(x+7)-5 = x <=>sqrt(x+7)=x+5
B=x+5>=0 ==> D: x>=-5
x+7=(x+5)^2 ==> x=-6 or x=-3
-6 ejecred as not in D
-3 is solution as -3>=-5 .

[aku]

Square root function only utilizes the positive square root.
less than -5, function x+5 is negative.
So -6 solution is omitted.

[tmeminem]

in 10x you only took away the x.. how do you get 9 out of that? I find this extremely confusing. Thank you for your help.

[jacobstorey]

How do I find the restrictions of the x if there is an exponent greater than 1 on the x value in the radical?

[hamiltonbitches]

everytime i watch your videos i just think about how lucky your students are to have you :, ( my teachers werent great in high school so now i struggle sometimes in college

[evelynramirez]

Its 2019 and this video has helped me wow can't thank you enough. Im from AZ btw.

[JamesWalton-ujkf]

why do the signs change when you get to the end ? the 6 and 3 were positive but you changed them to negitive???
