What you will learn! 1. How to identify and classify polynomials. 2. How to find the degree of a polynomial.

PolynomialBinomial Trinomial Degree

What you really need to know! Polynomials are classified according to the number of terms they have. A monomial has one term, a binomial has two terms, and a trinomial has three terms.

What you really need to know! A polynomial also has a degree. The degree of a polynomial is the same as that of the term with the greatest degree. The degree of a term is the sum of the exponents of its variables.

What you really need to know! The exponent of a variable in a monomial must be a whole number, and the variable cannot be in the denominator or under a radical sign.

Example 1a: Determine whether the expression is a polynomial. If it is, classify it as a monomial, binomial, or trinomial. Not a polynomial!

Example 1b: Determine whether the expression is a polynomial. If it is, classify it as a monomial, binomial, or trinomial. Yes ; Binomial

Example 2a: Find the degree of each monomial. 4 th degree

Example 2b: Find the degree of each monomial = 11 th degree

Example 3a: Find the degree of each polynomial = 7 th degree

Example 3b: Find the degree of each polynomial = 7 th degree

Example 4: The formula for the surface area (A) of a cube is A = 6s 2, where s is the side length. Find the degree of the polynomial. 2 nd degree
