Solving Quadratic Equations 1.14 - Solution

arrow_back Return to Solving Quadratic Equations

We want to use the given graph to determine the solutions of the related quadratic equation. The solutions of these equations are the coordinates of the points of intersection of the parabola and the axis. Recall that a quadratic equation can have two, one, or no solutions. Let's consider the graph.

This graph crosses the axis twice, so its related equation, has two solutions. We can see that those solutions are and
