Basically just factor the numerator and denominator, and make the latter multiplicities negative.

No, really. I don't understand and need you to elaborate! Are you talking about a single polynomial in which some of the terms have negative exponents? Or a rational expression where the numerator and denominator are polynomials?

The first case can easily by transformed by multiplying by x^n, with n being the lowest exponent in the polynomial, right? Then FACTORS will find a factor 0 with multiplicity n that wasn't there in the original. Am I even going in the right direction?
The second case is more problematic, since FACTORS accepts only a vector for now, how do you express the rational as a vector? It's best left as 2 vectors, then you can use FACTORS independently.
