When solving the radical; SQRT12x = 1 + x
It says first step:
Square both sides:
=
1 – 2x = 1 + 2x + x^2
I am confused about where this part of the equation is coming from:
\/
1 – 2x = 1 + 2x + x^2

Best ResponseYou've already chosen the best response.0Of course it will, then you'll move on to fun things like (x^2 + 35x + 5)(3x^2 + 2x + 1)
