Homework Help: Using partial fractions - why is it Ax+B/x^2 and not A/x + B/x^2?

  1. Jan 19, 2010 #1
    Partial fractions of (-2x2+10x+8)/[x2(x+2)]

    I initally thought that it was A/x + Bx+C/x2 + D/x+2 but you really just do Ax+B/x2 + C/x+2 ...can anyone explain why the "x2" isn't split?

    A/x+(B+Cx)/x^2=A/x+B/x^2+C*x/x^2=A/x+C/x+B/x^2. Doesn't that make the C term sort of redundant?
