Question: Problem simplifying complex expresions.

Dear all,
When I try to simplify the expresion z+conjugate(z) I get, as expected, 2*Re(z).

The problem arises when I try to do the same with a more complicated expression as z1*conjugate(z2)+conjugate(z1)*z2. Trying to simplify this Maple only give me back the expression with nochange. The expresion is equivalent to the first example so I expected to get 2Re(z1*conjugate(z2)).

Does anybody know how to solve this problem?
Thank you in advance!
