Answer:
Step-by-step explanation:
A term, loosely defined, is a product of numbers and variables. Terms are separated from one another with a + or a - sign. So we have 2 terms here.
The degree of the polynomial, because it is just in terms of x and no other variable, is the highest degree'd term. Our highest degree of x is 3, so this is a third degree polynomial.
It is classified by its number of terms:
1 term is a monomial, 2 terms is a binomial, 3 is a trinomial, and anything higher is just called a "polynomial". This has 2 terms so it is a binomial.
