8.4 Polynomials Objective: To be able to identify polynomials. find the degree of a polynomial. Objective: To be able to identify polynomials. find the degree of a polynomial.

Remember… A monomial is an expression that is a number, a variable, or a product of a number and one or more variables. (Pretty much, its anything that is alone or connected ONLY by multiplication!) 79xy-13xy 2 z0-3 No variables in the denominator!

Monomials The degree of a monomial is the sum of all of the exponents of its variables. Example 1: Find the degree of the monomial. a.8 Degree 0 b.13x Degree 1

Monomials Example 2: Find the degree of the monomial. 8xy 4 z 2 = Degree 7

Polynomials A polynomial is a monomial or the sum or difference of two or more monomials. Check list:  No variable in the bottom of ANY term  No negative exponents in ANY term  All exponents are whole numbers (no fractions!) Polynomial or Not?

Polynomials Standard form of a polynomial means that the degrees of its monomial terms are in order from greatest to least. (DESCENDING ORDER!) *ASCENDING ORDER goes from least to greatest. The degree of a polynomial is the greatest degree of ANY term in the polynomial.
