Tell whether the expression is a polynomial.
Key Vocabulary degree of a monomial the sum of the exponents of the variables in the monomial The degree of a nonzero constant term is 0. degree of a polynomial the greatest degree of its terms
Key Vocabulary leading coefficient the coefficient of the first term, when a polynomial is written so that the exponents of a variable decrease from left to right
Write the polynomial so that the exponents decrease from left to right. Identify the degree and leading coefficient of the polynomial.
