Unit 1: Basic Algebra Concepts
We begin by quickly reviewing the basic concepts you will need to understand as you begin your study of algebra. If you have taken a prealgebra course, you may be familiar with some of these concepts. With practice, every student, regardless of background, can grasp these concepts.
Completing this unit should take you approximately 26 hours.
Unit 2: Solving Linear Inequalities and Graphing
In this unit, you will learn to apply the concept of solving equations to solve problems involving linear inequalities. You will also learn how to graph a straight line, use different methods to find the slope and intercept of a line, and interpret slope and intercept. You will learn more about types of straight lines.
Completing this unit should take you approximately 20 hours.
Unit 3: Exponents and Polynomials
This section introduces you to the concept of evaluating exponents, converting scientific notations to decimal notations, and vice versa. You will apply these concepts to evaluating polynomial expressions.
Completing this unit should take you approximately 19 hours.
Unit 4: Factoring Polynomials
This unit expands on what you learned in Unit 3. In Unit 4, you will learn to factor the greatest common factor by grouping and other factoring methods. Because factoring and distribution are opposite actions, you will be able to determine whether you have factored correctly by going in the opposite direction, which is distributing through multiplication.
Completing this unit should take you approximately 19 hours.
Unit 5: Rational Expressions
In this unit, you will learn how to evaluate rational expressions and perform operations such as addition, multiplication, and division involving rational expressions. You will apply the concept of multiplying rational expressions to dimensional analysis, where you will convert units from single/dual unit of measurement to another.
Completing this unit should take you approximately 17 hours.
