Any polynomial written in standard form has a unique constant term, which can be considered a coefficient of x 0. In particular, the constant term will always be the lowest degree term of the polynomial.This also applies to multivariate polynomials.as a constant term of â4, which can be considered to be the coefficient of x 0 y 0, where the variables are become eliminated by exponentiated to 0 (any number exponentiated to 0 becomes 1).
