# How to integrate this function?

I have a problem with this integral:

Integrate[(( A x (x^2-1)^(5/2))/(B x^2+C)) Exp[-Subscript[z, 0]x],{x,1,Infinity}]

where $A$, $B$, $C$, and $z_0$ are constants.

I'm trying to use Mathematica 8 to solve it, but this diverges.

Maybe I'm doing something wrong. Otherwise, please tell me if there is some kind of algorithm to solve integrals like this.

Perhaps knowing the values of the constants would help. –  Sjoerd C. de Vries Oct 23 at 18:39
This is not a math forum; you shouldn't expect help from here with anything but Mathematica code. –  Svend Tveskæg Oct 24 at 15:33
