# Ch 9: Algebra: Polynomials

Learn about polynomials through the following online video lessons and quizzes. Find out about FOIL, the area method, quadratic equations, synthetic division and more.

## Algebra: Polynomials - Chapter Summary

Lessons in this chapter show you that working with variables doesn't have to be difficult. You can practice various ways to multiply binomials, including the FOIL, claw & face and area methods. Professional instructors show you that factoring is actually the FOIL method performed backwards, and they give you plenty of examples to test your competency in this area.

As you work your way through this chapter, you can find out that synthetic division is really just a quick way to divide polynomials by monomials. You can also learn how to solve quadratic equations by factoring, and determine how to complete the square to find the spot where the maximum or minimum parabola lies. Some of the key topics included in this chapter are listed below:

• Adding, subtracting and multiplying polynomials
• Using FOIL (firsts, outsides, insides, lasts) and the area method to multiply binomials
• Dividing polynomials with long division and with synthetic division
• Completing the square
• Solving equations with the quadratic formula

This chapter provides ample practice problems with accompanying detailed solutions. The lessons are available in both video and written transcript formats. By taking the quiz at the end of each lesson, you can track your progress and discover any topics that might need more attention. Watch the videos as many times as you like, or use the video tags to get quick access to specific parts of a video lesson. In addition, there are links to text lessons that will explain related key concepts and terms.
