I think you might check out Maple, because its algorithms at least used to
be open (ten years ago). Andre Heck wrote a book "Introduction to Maple".

In general though there is nothing such a general principle of
simplification. Expanding (x^n -1)/(x - 1) may sometimes be a good idea,
at other times not. If you represent polynomials as functions N -> set of
coefficient values, then expanding can take place also for large N. And so
on. There is a newsgroup sci.math.symbolic, which can perhaps provide more
info.
