Hi! I was wondering if anyone might be willing to check my answers for these... I have a suspiscion they are wrong, but I don't have any correct answers to compare them against. If I got them wrong, would you mind giving a brief explanation? Thank you for your help! (x^2-1)+(-2x+3) (I got 2x+x^2+2).

(X^2-1) (x^2+-9) (I got x^3+-12)

(x^2+-9)-(x+-3) (I got x+12)

f(g(x)) F=3x-4 G=(-x^2)I got -3x^3+4x^2

f(g(x))F=-2x G+-2x^2+3 I got 4x^3+-6x
