Using Parabolas to Solve Quadratic Equations

Students learn how to find the solutions to a quadratic equation using graphs.  Learning progresses from solving a quadratic when the parabola is drawn to plotting their own graph and identifying the number of solutions the equation has.
Differentiated Learning Objectives
• All students should be able to plot solve a quadratic equation in the form y = x2 + a graphically.
• Most students should be able to solve a quadratic equation graphical method.
• Some students should be able to use graphical methods to explain why some quadratics cannot be solved.
