How to decompose the formula?



Dear All :
I have one question with the following formula : X is discrete
FQ:= Sum (re(x)*ln(re(x))), I have value
Q1:=Sum(r1(x)*ln(r1(x))) and
Q2:=sum(r2(x)*ln(r2(x))),
also I know
the relation of re(x) , r1(x) and r2(x).
re(x)= convolution of r1(x) and r2(x);
I tried to use definition and decompose the FQ from current space ,
but it cannot work. The ln prohibit that method.
Is there any way I can use Q1and Q2 to express the FQ?
Thanks for any hint.
