Main Question or Discussion Point

Ok, I have been trying to divide this polynomial.

(x^3-15x-7)/(x^2-3x-3)

After I factor the first part I get stuck. This is last problem on my homework and is due in less than an hour. Please some one help me out. Thanks

_x__+3_________
(x^3-15x-7)|x^2-3x-3
-
x^3-3x^2-3x
------------
3x^2-12x-7
-
3x^2-9x-9
------------
-3x+2

so the answer is (x+3)*(x^2-3x-3)-3x+2=x^3-15x-7

im sorry for my long division it's just the lack of other way of doing it.
