You mention simplify and expand - which probably means that you are in fact *not* working in the quotient field of a polynomial ring, because simplify and expand are typical methods of symbolic expressions. Could you tell us the result of f.parent()? If f.parent() is a quotient field, then methods like f.numerator() and f.denominator() will provide you with the polynomials a and b you were looking for.
