# Ch 15: High School Algebra: Graphing and Factoring Quadratic Equations

Watch online video lessons and learn about the different aspects of graphing and factoring quadratic equations. Use the self-assessment quizzes to test your knowledge of the material.

## Graphing and Factoring Quadratic Equations - Chapter Summary and Learning Objectives

This chapter is tasked with showing how real-world algebraic data can be displayed through graphs and tables. In these lessons our instructors will teach you how factor and solve quadratic equations. You will also come to know the difference between trinomials, polynomials and binomials. We offer a few lessons that allow you to practice concepts through examples that we supply. This chapter is designed to teach you how to:

• Identify and define the different parts of a parabola
• Use the FOIL technique to multiply binomials
• Factor to solve a quadratic equation
• Plot points on a scatter plot and line graphs
• Complete the square
