what is a binomial

In algebra, a binomial is a polynomial that consists of two terms, each of which is a monomial. It is the simplest kind of polynomial after the monomials. An example of a binomial is (3x^2 + 2). Another way to express a binomial is as the sum or difference between two or more monomials. For example, (2xy + 7y) is a binomial because it has two unlike terms connected through an addition operator. Binomials are used in various algebraic operations, such as factoring and expansion. They are an important concept in algebra and are used in various mathematical applications.
