x2(squared)-4x+4 I would factor this into (X - 2)(X - 2) If you don't know the rules for factoring, post, and we can show you how to do it. I don't know the factoring rules. My algebra teacher couldn't teach.

Algebra

Solve the equation. Use factoring or the quadratic formula, whichever is appropriate. Try factoring first. If you have any difficulty factoring, then go right to the quadratic formula. (Enter your answers as a comma-separated list.) (x+2)^2 + (x-7)(x-2)=16
