expand and simplify:2(x+2)squared-(2x-1)(x+2) 2x(x-2)+5x(x÷3)-x(3x-1) (5x-3)(2xsquared+3x-3) solve for x:(x-2)squared+3x-2=(x+3)squared

Answer 1

I'm having a hard time parsing your text. Is it all one expression? What is the significance of the spaces? Or are there three separate expressions?

2(x+2)^2-(2x-1)(x+2) 2x(x-2)+5x(x/3)-x(3x-1) (5x-3)(2x^2+3x-3)

As for the other one, I think it's

(x-2)^2+3x-2 = (x+3)^2

well, you start out by expanding stuff and collecting like powers:

x^2-4x+4+3x-2 = x^2+6x+9
x^2-x+2 = =x^2+6x+9
7x = -7
x = -1
