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

Work Step by Step

The answer to problem #3 is: "A binomial is a polynomial with exactly three 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 three terms," we know such an equation is trinomial.
