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...

comment FindMaxValue vs FindMaximum
Thanks, first i thought it was giving me the same problem as FindMaximum, but now i see you also can give 2 starting points to FindArgMax. So my problem with FindMaximum is the use of derivatives then?
