The correct answer is linear binomial.​

​Monomial is a real number, a variable or the product of a real number and one or more variables with whole exponents.

A polynomial​ is a monomial or the sum or difference of two or more terms.

​

In order to name this polynomial, you need to know the number of terms and the degree.

The degree of a polynomial is the biggest exponent in a polynomial.

​0 degree: constant | 1 degree: linear | 2 degree: quadratic | 3 degree: cubic | 4+ degree: (that number) degree

​

The terms in a polynomial are separated by a + and -.​

​1 term: monomial | 2 terms: binomial | 3 terms: trinomial | 4+ terms: polynomial
