Homework Help: Fraction Reducing

  1. Dec 23, 2004 #1
    Hey guys,

    I'm working on this project for my research and I am having trouble reducing a fraction. The fraction is:

    (bc-ab) / (a^3 - ac^2 - 2ab^2 + 2b^2c)

    I am almost positive that I can end up with only a (b) on top but I am not sure how. I had an idea:

    (b(c-a)) / (a(a^2-c^2) - 2b^2(a - c))

    I want to factor out a (a - c) on the bottom but can't because I have (a^2 - c^2).

    a^2-c^2= (a-c)(a+c), so you can factor out (a-c) from the denominator.
