This video lesson excerpt by Professor Burger shows what while sometrigonometric equations cannot be factored, they may be solved by applying the quadratic formula. This is a production of MindBites.

The insructor uses y=x^2 to give a sense of why the change in the change of y (or the change in the slope) is constant. This instructor in this video, Sal Khan, explains quadratic models.

This lesson takes students step by step in a tutorial formation using the quadratic formula. The student will see three different situations where the equations have 2, 1, or no real solutions. Teacher should demonstrate to students why there are 2, ...1, or no real solutions.[more]

This lesson will teach you how to solve a quadratic equation using Quadratic Formula and discuss the different type of solutions of a quadratic equation. Duration: 7:21

This instructor begins this lesson by explaining what the quadratic formula is and how it is used. The instructor works through a variety of examples explaining step by step how to use the quadratic formula to solve a quadratic equation. It would b...e easy to work the problems while following along with the instructor.[more]

Using the quadratic formula to solve equations may bring one, two, or no algebraic solutions. The quadratic formula is special to quadratic equations. Run time 03:24.
