This section describes how to determine the solution(s) of a quadratic equation using graphs.

The solutions of quadratic equations are actually the x-intercepts. The point(s) where the parabola crosses the x-axis is called the x-intercept.

• Recall that x-intercepts can also be called roots or zeros.
• The x-intercepts for the above graph are (-2, 0) and (2, 0).
• The solution set is {-2, 2}.
