This lesson covers the method of completing the square as a tool for solving quadratic equations. It begins with a review of perfect square trinomials and provides examples of factoring them. The lesson then explains how to create perfect square trinomials and solve quadratic equations using this method. It concludes with challenge problems to test understanding.

What is the primary goal of completing the square in quadratic equations?

• To make the quadratic equation easier to factor

• To transform the equation into a linear form

• To eliminate the quadratic term

• To create a perfect square trinomial
