Hi all,

I'm working heavily with symbolic computation, because otherwise for the problem I'm working on, the math would be entirely unmanageable.

A problem that I've encountered (and can't seem to figure out) is that I need to perform something like this...

\sum _{n=0}^{\text{nmax}} (x-2) x f(n,x)

where the desired output corresponds to...

5 (\text{nmax}+1)-2 x f(n,x).

But the actual output given by Mathematica is

\sum _{n=0}^{\text{nmax}} (x-2) x f(n,x).

In other words, the ReplaceAll command doesn't do anything. It doesn't seem to recognize that $x^2 f(n,x)$ is present in the sum.

This is incredibly important for me to be able to continue, so I'd really appreciate if anyone knows what the problem is, or has a possible solution.

I appreciate your time.

Thanks,
Bill
