Partial Fractions

  1. Sep 28, 2013 #1
    1. The problem statement, all variables and given/known data

    Write out the form of the partial fraction decomposition of not determine the numerical values of the coefficients.

    2. Relevant equations

    x^4 -2x^3 + x^2 +2x -1 / x^2 -2x +1

    3. The attempt at a solution

    I did the division and I got x^2 + ((2x-1)) / (x^2 -2x +1)

    So I took
    ((2x-1)) / (x^2 -2x +1) = Ax + B / x^2 -2x +1

    Is this right? It has been forever since I did these.

    It's right, but it's not a complete partial fraction expansion. x^2-2x+1 factors into (x-1)(x-1). Review partial fractions.
