       \brief Return the nonzero subresultants of \c p and \c q with respect to the "variable" \c x.
       
       \pre \c p, \c q and \c x are Z3 expressions where \c p and \c q are arithmetic terms.
       Note that, any subterm that cannot be viewed as a polynomial is assumed to be a variable.
       Example: f(a) is a considered to be a variable in the polynomial   
                  
       f(a)*f(a) + 2*f(a) + 1
