Course: Algebra II / Elementary Algebra
Topic: Exponents and Polynomials
Subtopic: Polynomial Operations I - Simplify, Add, & Subtract

Overview

Polynomials are algebraic expressions that (usually) contain several terms such as x5-2x4+5x3+6x-9. Remember when you were in elementary school and you were just learning about numbers? You learned to add and subtract, later multiply, and then the dreaded long divide. Well, that is what we are going to do here except we will be performing these operations with polynomial expressions not plain numbers. So put your algebra hats on and get your pencils warmed up, because we are going to embark on a "polynomic" adventure!

Objectives

By the end of this topic you should know and be prepared to be tested on:

• 6.3.1 Understand the definition of a polynomial
• 6.3.2 Evaluate a polynomial for a given value of a variable
• 6.3.3 Add or subtract two or more polynomials and simplify by collecting like terms
• 6.3.4 Recognize when two polynomials are "opposites" of one another
• 6.3.5 Find the "opposite" of a given polynomial
• 6.3.6 Determine the degree of a term (both single and multi-variable terms)
• 6.3.7 Determine the degree of a polynomial (both single and multi-variable polynomials)
• 6.3.8 Write a polynomial in standard descending order (both single and multi-variable polynomials)

Terminology

Define: coefficient, variable, exponent, term, polynomial, single-variable vs. multi-variable polynomial, opposite, opposite of a polynomial, degree of a term, degree of a polynomial, standard descending order (SDO)

Text Notes

Although your textbook may stick to single variable polynomials at this point, we will begin to discuss multi-variable polynomials in class now.
