Give the name (monomial, binomial, trinomial, etc.) and the degree of the
polynomial.
5x3 - x2 + 2

Step-by-step explanation:

Monomial, binomial, and trinomial refer to the number of terms in a polynomial. Each term is separated by another with either a + or a -. The degree is the highest exponent on the variable.

Our number of terms is 3, so this is a trinomial.

Our highest exponent is also a 3, so this is a rd degree polynomial.
