In this lesson, you will learn to complete the square to solve quadratic equations, in which the squared term has a coefficient other than 1.

When you finish this lesson, you will be able to:

• Complete the square for quadratic expressions of the form $a{x}^2+bx+c$ when $a$ is not 1 and explain the process.
• Solve quadratic equations in which the squared term coefficient is not 1 by completing the square.

Here are the activities that will help you reach those goals:
