**Grade 9 Algebra I Module 4 Lesson 13**

How can I solve a quadratic equation if I cannot factor it? In this lesson, Mr. Donovan will demonstrate how to use completing the square in order to solve quadratic equations that are difficult to factor. Students will need paper, a pencil, a calculator and a highlighter. If you have access to a workbook, or a printer, we also suggest using the Classwork for the lesson, which is available using the link below the video.
