    Question Help with Partial Fraction Decomp

    Can you help me find the partial fraction decomposition (but do not solve for the constants)?

    (3x^3-x+5)/x^3(x^2+4)^2(x-1)

    Thank you!

    It's gonna be a long one.

    You will have:

    \frac{Ax+B}{(x^{2}+4)^{2}}+\frac{Cx+D}{(x^{2}+4)}+  \frac{E}{x-1}+\frac{F}{x}+\frac{G}{x^{2}}+\frac{H}{x^{3}}=3x^  {3}-x+5

    I'm with Plato on this. Run it through a calculator. My TI-92 gave me the PFD in about 2 seconds.
