Using the Quadratic Formula to Locate X-Intercepts

The quadratic formula, though scary to look at, will allow you to determine where the x-intercepts of a parabola will be, if they exist. Remember, the discriminant can be used to help you determine whether the parabola will have 0, 1, or 2 x-intercepts. The entire quadratic formula can used to determine intercept locations provided the discriminant renders at least one solution possible.

Tonight's Homework: Lesson 9.5 ( 23 - 31, 44 - 50, FCO and 53 - 55 ). Note: All assigned problems should have "pretty" answers (not ones including square roots). Double check your work if you get an answer that includes a radical sign in it.

For all who missed today's class (there were 6 of you!!), I hope you are doing well. Feel free to knock on my window Tuesday morning around 8:20 if you have trouble with tonight's homework. Most of all, take care of yourselves!
