Solving quadratics allows us to find the x-values where the parabola crosses the x-axis. These are the solutions to our quadratic equation. They are referred to as zeros, roots, and x-intercepts.

For example, in the picture below, the parabola crosses the x-axis at -1 and 2. This means that the solutions to the equation y=x^2-x-2 are -1 and 2. There are a few different ways to solve quadratics to obtain these x-intercept solutions. These include solving by algebraic manipulation, factoring, using the quadratic formula, and completing the square. You will learn how to use these different methods to solve quadratics as you move through this studio.
