Solve Quadratic Equations by Factoring

This is a refresher on solving quadratic equations using factoring methods. This section assumes you have been exposed to methods for factoring previously.

Quadratic Equations

Learning Objectives

In this section, you will:

  • Solve quadratic equations by factoring.
  • Solve quadratic equations by the square root property.
  • Solve quadratic equations by completing the square.
  • Solve quadratic equations by using the quadratic formula.

Figure 1


The computer monitor on the left in Figure 1 is a 23.6-inch model and the one on the right is a 27-inch model. Proportionally, the monitors appear very similar. If there is a limited amount of space and we desire the largest monitor possible, how do we decide which one to choose? In this section, we will learn how to solve problems such as this using four different methods.
