Homework Help: Simplifying an algebraic fraction with factors

  1. Jun 29, 2012 #1
    1. The problem statement, all variables and given/known data

    Simplify the following expression: x3(1-x2) / x(x-1)

    2. Relevant equations

    3. The attempt at a solution

    I know that the top can be factored to x3(1-x)(1+x) to give x3(1-x)(1+x) / x(x-1) . However, after this step I seem to just go round in circles. I got an answer of 2 on one occasion but I do not believe this is correct. Help would be appreciated.

    1 - x = -(-1 + x) = -(x - 1)
    Does that help?
