Help simplifying a rational expression?

  1. Oct 8, 2012 #1
    1. The problem statement, all variables and given/known data

    [itex]\frac{x^2}{(x^2 -1)}[/itex]

    2. Relevant equations

    N/A

    3. The attempt at a solution
    I know the solution is supposed to be 1+[itex]\frac{1}{2(x-1)}[/itex]-[itex]\frac{1}{2(x+1)}[/itex] and when I did long division, I got 1+[itex]\frac{1}{(x^2-1)}[/itex] , so I'm making progress, but I'm not quite there. What should I try for my next step?

    The next step is to use partial fractions.

    Are you familiar with them?
