12th grade

can anyone explain how to divide in algebra? I have this problem:
(15x2-24+9)/(3x-3)
I am not looking for someone to give me the answer straight out I just need to know how to get there.

  1. Start in the same way as you would do long division.

    Set it up as
    _________
    (3x-3)|15x2-24x+9

    then how many times does 3x go into 15x^2, which is 5x

    5x
    _________
    (3x-3)|15x2-24x+9

    15x2-15x (from 5x times (3x-3)


    subtract

    5x
    _________
    (3x-3)|15x2-24x+9

    15x2-15x
    ________
    -9x+9


    I hope the formatting holds. Is this OK?

  2. The formatting didn't work 8-((

    I hope you get the idea. I'll try again with dots for spaces.
