#### Answer

"A binomial is a polynomial with exactly two terms." The answer is "binomial".

#### Work Step by Step

The answer to problem #1 is: "A binomial is a polynomial with exactly two terms." So, the answer is "binomial".
It is helpful to remember that the prefix of each Polynomial type signifies a certain number:
In the Polynomial type monomial, its prefix is mono-, meaning 1. So, monomials only have 1 term in an equation.
The prefix bi- for binomial means 2. So, binomials have 2 terms in an equation.
The prefix tri- for trinomials means 3. So, trinomials have 3 terms in an equation.
Based on the supplied information as an equation containing "exactly two terms," we know such an equation is binomial.
