Polynomial.

Trinomial.

A quick Google search will tell you that "polynomial" simply means "an expression of more than two algebraic terms...".

$2 x^{- 3} - 4 x + 1$ $2 x^(- 3) - 4 x + 1$ consists of three algebraic terms.

So it is a "trinomial".

How do you determine if 2x^-3-4x+12x−3−4x+12x^-3-4x+1 is a polynomial and if so, is it a monomial, binomial, or trinomial?
