Using the Quadratic Formula to Determine x-Intercepts of a Parabola

We reviewed what the standard form of a quadratic equation looks like. Remember, having a positive "a" term is desirable, and may be required by future math teachers.

Using the quadratic formula, we learned how to find the x-intercepts of certain parabolas. Remember, not all parabolas have x-intercepts. You can tell how many x-intercepts a parabola has by evaluating the discriminant.
