The terms of a polynomial are_____________ monomials. 

• Always; A polynomial is a monomial or sum of monomials, and each monomial is a term of the polynomial.

• Always; A polynomial is a binomial or sum of monomials, and a monomial can be a term of the polynomial.

• Sometimes; A polynomial is a sum of monomials, binomials, and trinomials, and a monomial can be a term of the polynomial.

• Never; A polynomial is a sum of binomials and trinomials, not monomials.
