Homework Help: Partial fractions

  1. Jul 8, 2009 #1
    1. The problem statement, all variables and given/known data
    partial fractions


    (-x^2+x+3)/((x-2)^2(x+1)) = A/(x-2) + B/((x-2)^2) + C/(x+1)

    is my partial fractions set up right

    A= -1/9 B = 1/3 C=1/9

    The setup looks right. I'm not so sure about your value for A though.

    i think A=-10/9
