Hi experts, Let f[x_] := c/(x - p) + c\[Conjugate]/(x - p\[Conjugate]) I am interested in local extrema Solve[D[f[x], x] == 0, x] Mathematica gives me a list. I plug those values into f again. Using the Simplify command I get expression as sqrt(- c conjugate c ( p - conjugate p ) ^2 ) Is there a way that Mathematica simplifies that to 4*(abs (c))^2 (Im p)^2 cheers Thomas
