always check the domain before squaring.

Alternative:just find the domain of the two functions, take intersection and u will be left with 1 and -1, check them by putting in the equation 😀😀

Quick but good video, we can also notice that if one of the expressions under the square root was not equal to zero (x^2 not equal to one) then one would be positive and the other one, negative which wouldn't satisfy the equation

like this question, great job solving it

The question was too easy but good for a short video

I noticed something in your question:

Find the misteak:

√(1-x^2) = √(x^2-1)

√((1+x)(1-x)) = √((x+1)(x-1))

(√(x+1))(√(1-x)) = (√(x+1))(√(x-1))

√((-1)(x-1)) = √(x-1)

(√-1)(√(x-1)) = √(x-1)

√-1 = 1

I got this recommended for some reason lol

I like these videos, I’m in highschool and I forget that I can solve by squaring both sides 😅

[xtraPathshala]

too easy but keep on to help for students

[Loots]

yeah but can you find x if it's: 4x=1
