    I just typed all this up
    Spoiler:

    Here is an example:

    \frac{2x^2+4}{(x-2)^2(x+4)} \equiv \frac{A}{(x-2)} + \frac{B}{(x-2)^2} + \frac{C}{x+4}

    Multiply throughout by (x-2)^2(x+4)

    2x^2+4 = A(x-2)(x+4) + B(x+4) + C(x-2)^2

    We want to find each constant, so get rid of each one by getting values to 0.

    Let x = 2
    2(2)^2 + 4 = A(2-2)(2+4) + B(2+4) + C(2-2)^2
    12 = 6B \therefore B = 2

    Let x = -4
    2(-4)^2 + 4 = A(-4-2)(-4+4) + B(-4+4) + C(-4-2)^2
    36 = 36C \therefore C = 1

    Let x = 0
    2(0)^2 + 4 = A(0-2)(0+4) + B(0+4) + C(0-2)^2
    4 = -8A + 4B + 4C
    Sub in values we know:
    4 = -8A + 8 + 4 \therefore -8 = -8A \therefore A = 1

    \frac{2x^2+4}{(x-2)^2(x+4)} \equiv \frac{1}{(x-2)} + \frac{2}{(x-2)^2} + \frac{1}{x+4}

    It seems the person you wrote that for can't understand simple maths...even after telling him exactly how to answer the question!
    :facepalm:
    It must have taken you ages to write that all in latex :eek:
