Khan Academy: Quadratic Equations: Graphing a Parabola With a Table of Values

This resource has everything you need to know about solving quadratic equations. Factoring, completing the square, the quadratic formula, and using the discriminant are all there with with worked out examples and a 25 problem...

Moving parabolas off of graph paper and into the real world is the task at hand in this detailed poster project. First, learners perform a cumulative activity identifying many characteristics of an assigned quadratic equation. Next, they...

In this solving applications worksheet, students translate word problems to number sentences. They solve the created quadratic equation. This three-page worksheet contains 12 problems.

In this factoring worksheet, learners factor 20 quadratic equations.  The last two questions use constants instead of integers and an answer key is provided.

The instructor continues solving quadratic equations by plugging values into the quadratic formula. These examples are more difficult because the answers do not correspond to whole numbers.

Sal first solves some equations using the factoring method he has already taught. Next, he introduces the quadratic formula and demonstrates how to plug the numbers from the quadratic equation into the quadratic formula. He then solves...

Introducing square roots into the quadratic equation mix, Sal takes care to address the ways viewers might go about solving the problems, both correctly and incorrectly. The video is an integral step in not only Sal's algebra series, but...

With his trusty graphing calculator, Sal begins his lecture on solving quadratic functions by graphing. The video is a good way to show young mathematicians not only how to use the graphing calculator (which Sal describes as "archaic"...

Focusing on the intuitive nature of algebra and factoring, Sal demonstrates how to efficiently factor quadratic equations. This video would be great to show in class after a lecture on quadratics, or to assign in a computer lab (or...

Transformations of parabolas to fit a particular quadratic equation is taught through this lesson.  In this transforming parabolas to fit a particular quadratic equation lesson, students describe the transformations of the parabola...
