Multivariate polynomial elimination question
I have a polynomial P[x,a,b] with rational coefficents of degree 15 in x. It is quartic w.r.t. the variable a, and a cubic w.r.t. b^2. I wish to recover the degree 60 and degree 90 (w.r.t. x) polynomials Q[x,b] and R[x,a] by eliminating a and b^2 respectively. I've tried naively using Eliminate[P==0,a] but this just returns TRUE. Is it possible to do this by some other means?
