A binomial is a polynomial which is the sum of two [[monomial]]s. A binomial in a single indeterminate (also known as a [[univariate]] binomial) can be written in the form
:<math>a x^m  bx^n \,,</math>
where {{math''a''}} and {{math''b''}} are [[number]]s, and {{math''m''}} and {{math''n''}} are distinct [[nonnegative integer]]s and {{math''abcdefghijklmnopqrstuvwxyzx''}} is a symbol which is called an [[indeterminate (variable)indeterminate]] or, for historical reasons, a [[variable (mathematics)variable]]. In the context of [[Laurent polynomial]]s, a ''Laurent binomial'', often simply called a ''binomial'', is similarly defined, but the exponents {{math''m''}} and {{math''n''}} may be negative.
