# Binomial

Pronunciation: /baɪˈnoʊ.mi.əl/ Explain

A binomial is a polynomial with two terms, such as 2x + 3y.[2]

The special binomial a2-b2 can be factored as (a-b)(a+b). a and b can be any monomial term.

The binomial theorem can be used to find any particular term of a binomial with an integer exponent: (a+b)n, n ∈ ℕ.
