Ah, I forgot that if factor is not a number, it won't distribute automatically. You'll want to do something like
n, d = expr.as_numer_denom() expand(n*factor)/expand(d*factor) The way it is now, factor just immediately cancels. And by the way, if your goal is to write a rational function in reduced terms, you can use cancel() or factor() (the latter will also factor the numerator and denominator).
