Question

Solve: 2x^2 -4(x^2+2x-3)=5x-2(x^2-x-2)-7

Answer 1

Have you considered the Distributive Property followed by various simplifications?

Answer 2

Well I just went through the problem and got x=1. Is that the right answer?

Answer 3

Not a clue. Work it out for me and we'll see if you wander off.

Answer 4

Excellent demonstration! First line is no good.

You have -4x where you should have -4x^2

This is a little puzzling, because it doesn't seem to have bothered you. The second line looks fine. Why?

Looks pretty good, otherwise.
