How Do You Solve a Quadratic Equation with Two Solutions by Graphing?

Curated and Reviewed by Lesson Planet

There are many ways to solve a quadratic equation. Let's check out how to solve a quadratic equation by graphing. But first, let's find the axis of symmetry and the vertex before making a table of values. Write the values as ordered pairs and then graph them. Locate the places where the parabola crosses the x-axis and you will have the two solutions to the quadratic equation.
