Dividing polynomials

  1. Oct 15, 2003 #1
    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.
