comment Order of a pole
Ah nice, I understand. TransferFunctionPoles will give the solution multiple times in contrast to Solve. Thanks!

This only gives me the poles, not the order...

Thanks! This works. As alternatives you mean Reduce?

@Guesswhoitis. I really don't think it would be illuminating if I explicitly gave you this function. Also I just wanted to know if this was possible in general.

Yes @JohnMcGee it is a rational function.

comment Simplify does not simplify
The terms cancel each other when you perform the Square root: Sqrt[(wb Z - w xiR^4 Zb)^2/xiR^4] = (wb Z - w xiR^4 Zb)/xiR^2.

comment Root: Simplifying symbolic expression
Ok, I didn't realise this. It's just that I want to understand the output from for example Integrate[-((2 I \[Pi])/Sqrt[(r + A xiR - rb xiR^2)^2 - 4 (l xiR + w xiR^2 + Z) (wb - lb xiR + xiR^2 Zb)]),xiR] which gives an EllipticF[ArcSin[...]] from a gigantic expressions with a lot of Roots... I want to find the an expression for A wherefore this integral becomes zero but it's too complicated to understand so I wanted to simplify this integral...
