Polynomials Section 5.2
Definitions • Polynomial: Monomial or sum of monomials • Example: 7a2 + b + 6ac2 - 8ac • Like Terms: 2 monomials that are the same or differ only by their coefficients. • Example: 2x and 4x 3y and 3y • Terms: Monomials that make up polynomials
Identifying Polynomial • Monomials contain variables whose exponents can be written as whole numbers. • Is it a polynomial? • 7a2+ b + 6ac2 - 8ac • Yes, each monomial (term) has variables whose exponents are whole numbers
Degree • The degree of a polynomial is the highest degree among all terms.
