Math Help - Need help please! Confused!

simplify

(x^2-36)/(x^2+4x-12)/(x-3)/(x-2)

Solve for X

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

Sorry if this seems too easy but i'm really confused on these problems. I've look at examples but it's not helping at all. Any help will be appreciated.

2. consider the following factorisations

$x^2-36 = (x+6)(x-6)$

$x^2+4x-12 = (x-2)(x+6)$
