Answer 13

so you dont have to combine anhything?

hartnn gave you a short cut. if you used FOIL
on (x-3)(x-3) you would get 4 terms, 2 of which combine
x^2-3x-3x+9
now combine the -3x -3x

Answer 14

btw, that middle term should be negative.

Answer 15

If you know how, I would do FOIL to get the answer. It is good practice.
