Question

Solve for x

Answer 1

\[(x+5)^2 + 3 = (x-2)^2 \]

Answer 2

You need to multiply them out first. Use FOIL.

Answer 3

I know. You get x^2 + 28 = x^2 + 4

Answer 4

But the x^2 aspect confuses me

Answer 5

Actually, you would get if I'm not mistaken\[x^2 +10x+25=x^2-4x+4\]

Answer 6

Oh, yes. That's right. Sorry.

Answer 7

(x+5)(x+5) (x-2)(x-2)
x^2+10x+25+3=x^2-4x+4
The x^2 cancels out
14x+28=4
x= -1.714
