Knowledge_On-The-Go_Grade-9Grade 9 Algebra I Module 4 Lesson 15

Can we determine how many answers a quadratic equation has before solving the entire equation? Ms. Neill will demonstrate how to use the discriminant to determine the number of real solutions to a quadratic equation. 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.
