A polynomial with just one term, like - 9y 6, is a monomial. If a polynomial has two terms, like x 2 + 4, it is a binomial. A polynomial with three terms, like 4x 2 - 4xy + 1, is a trinomial. Expressions like 2x 2 - 5x + 3 , x 9 - 2x, and x + 1 x4 + 5 are not polynomials, because they cannot be written in the form anx n + an - 1x n - 1 + g + a1x + a0, where the exponents are all nonnegative integers and the coefﬁcients are all real numbers. a Addition and Subtraction If two terms of an expression have the same variables raised to the same powers, they are called like terms, or similar terms.
