1. Polynomials A monomial is a number, a variable, or the product of a number and one or more variables with whole number exponents. The degree of a monomial is the sum of the exponents of the variables in the monomial. A nonzero constant has degree 0. Examples of Monomials Degree: Non - Examples of Monomials

2. Polynomials What is the degree of each monomial? Practice 1: Practice 2: Practice 3

3. Polynomials A polynomial is a monomial or a sum of monomials. The degree of a polynomial is greatest degree of its terms. The leading coefficient of a polynomial is the coefficient of the first term of the polynomial when it is written so that the exponents of a variable decrease from left to right. Each monomial in a polynomial is called a term. A binomial is a polynomial with two terms. A trinomial is a polynomial with three terms. Examples of polynomialsDegreeLeading Coefficient Like Example 2 Like Example 3

4. Polynomials Write the polynomial so that the exponents decrease from left to right. Identify the degree and leading coefficient of the polynomial. Practice 4:Practice 5:

5. Polynomials Tell whether the expression is a polynomial. If it is a polynomial find its degree and classify it by the number terms. If it is not a polynomial explain. Example 5: Not a polynomial, because it has a negative exponent. Example 6: Yes, it is a 4 th degree trinomial. Practice 6: Practice 7

6. Polynomials Find the sum or difference. Example 7:

7. Polynomials Find the sum or difference. Example 8:
