# Ch 13: High School Algebra: Factoring

Watch online video lessons and learn about the different aspects of factoring. These lessons utilize engaging animations and on-screen graphics to help you quickly retain key information.

## Factoring - Chapter Summary and Learning Objectives

This chapter helps you understand the definitions for factor, coefficient, relatively prime and constant. Here our instructors will train you in the different ways factoring is used in real life and algebra. By the time you finish the video lessons, you should know the various ways factors are used to make a multiplication expression. Concepts covered during this chapter include how to:

• Find the prime factorization of a number
• Explain how to use grouping to factor
• Simplify fraction notation
• Use fraction notion when adding, subtracting, dividing and multiplying
• Combine variables and numbers
• Factor out terms in an expression
