What’s a Polynomial? Poly—more than one; many Nomial—term Polynomial—more than one term; many terms More specifically, a polynomial is an expression that meets the following conditions: • All terms have variables that are raised to positive, whole number exponents (no negative or fractional exponents) • None of the variables are in the denominator of a fraction
Degree of a Polynomial The degree of a polynomial is the highest degree of its terms. The degree of a term is the sum of the variable exponents.
Write a polynomial that meets the following criteria… • Has 1 variable • Has 3 terms • Has 2 coefficients • Is 4th degree
Naming Polynomials By Degree Constant—”0 degree” Linear—1st degree Quadratic—2nd degree Cubic—3rd degree Quartic—4th degree Quintic—5th degree 6th degree 7th degree By # of Terms Monomial—1 term Binomial—2 terms Trinomial—3 terms Polynomial—4+ terms Example: _______________ _______________ Quadratic Trinomial By degree By # terms
Name the following polynomials: 1. (linear binomial) 2. (5th degree polynomial) 3. 7 (constant monomial) 4. (quadratic trinomial)
