• 5.1: Functions
• 5.2: Polynomials
A polynomial is a many-termed mathematical expression, with terms separated by plus or minus signs. The coeﬃcients of a polynomial are the coeﬃcients of its terms.
• 5.3: Applications of Polynomials
• 5.4: Adding and Subtracting Polynomials
In this section we concentrate on adding and subtracting polynomial expressions, based on earlier work combining like terms in Ascending and Descending Powers.
• 5.5: Laws of Exponents
• 5.6: Multiplying Polynomials
In this section we will ﬁnd the products of polynomial expressions and functions. We start with the product of two monomials, then graduate to the product of a monomial and polynomial, and complete the study by ﬁnding the product of any two polynomials.
• 5.7: Special Products
This section is dedicated to explaining a number of important shortcuts for multiplying binomials. These are extremely important patterns that will produce the same products computed in previous sections. It is essential that readers practice until they become proﬁcient using each of the patterns presented in this section.
