# Thread: Help with Partial Fraction Decomp

1. ## 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!
Doris

2. 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.
