How do you determine if 3y^2-2 is a polynomial and if so, is it a monomial, binomial, or trinomial?

Oct 8, 2017

$3 {y}^{2} - 2$ is a binomial.
Some people believe that polynomials must have more than 2 terms while others believe it must have 2 OR more.

Explanation:

Definitions:
Monomial: consisting of ONE term
Binomial: consisting of TWO terms
Trinomial: consisting of THREE terms
Polynomial: consisting of SEVERAL terms

$3 {y}^{2} - 2$ has TWO terms, so it is a binomial
Some people believe that polynomials must have more than 2 terms while others believe it must have 2 OR more.

Poly means many, or at least more than one. So technically, a binomial is a polynomial.
