Degree of a Trinomial

In mathematics, a trinomial is a polynomial with exactly three terms, where a polynomial is a mathematical expression that is a sum of products of constants, variables, and/or positive integer powers of variables. The degree of a trinomial, or any polynomial, in one variable, is equal to the highest exponent of that variable.
