> PolynomialRing(ZZ, 'x') This is only an aside, but I should probably warn that (unlike var, say) this doesn't change x, so it might not do what you're thinking.
x is still an Expression, an element of the Symbolic Ring, and so f is also an Expression. You probably want to use something like sage: R.<x> = PolynomialRing(ZZ) sage: parent(x) Univariate Polynomial Ring in x over Integer Ring sage: f=x^3 + A*x +B sage: parent(f) Univariate Polynomial Ring in x over Integer Ring or R.<x> = ZZ[] or something.
