    partial fraction decomposition

    I need help with these two problems!!

    Write the partial fraction decomposition for the rational expression. Check your result algebraically and graphically using a graphing utility.

    1. (x^2-1) / (x(x^2 + 1))


    2. (x^2) / (x^4 - 2x^2 - 8)

    2. (x^2) / (x^4 - 2x^2 - 8)
    1. \frac{x^2}{x^4 - 2x^2 - 8}

    \frac{x^2}{(x^2+2)(x+2)(x-2)} = \frac{A}{x-2} + \frac{B}{x+2} + \frac{Cx +D}{x^2+2}

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

    \frac{x^2-1}{x(x^2+1)} = \frac{A}{x} + \frac{Bx +c}{x^2+1}

    Can you finish up?
