Algebra 2

Quadratic Equations and Functions are used to represent a wide range of data, from projectile motion to the area of rectangles. Basic concepts will be demonstrated such as how to use The Quadratic Formula and Completing the Square to find solutions to quadratic equations. Challenge yourself with Complex Numbers, which occur in Quadratic Equations with No Real Solutions. From visual representation with Graphing Quadratic Equations when b = 0 to Unreal Roots, this course provides insights into solving for quadratic functions.
