A polynomial with a single term, such as 5, -2xyz, or xy^4, is called what?

• A. Polynomial
• B. Monomial
• C. Binomial
• D. Monoid

Answer: (B)

A polynomial with a single term is called a monomial. The idea is that polynomials are built from terms added together, and a monomial is just one of those terms. A monomial can be a constant or a constant times variables raised to nonnegative integer powers, like 5, -2xyz, or xy^4. If there were two terms, it would be a binomial, and a general polynomial is a sum of such monomials. Monoid is a different concept entirely and isn’t about polynomials.
