This video explains how to use the quadratic formula to solve quadratic equations

This lesson will review and provide practice on how to use the quadratic formula. Learn to develop good habits using the formula and what different outcomes mean to the solution.

This video shows the process for working through two problems. The first shows how to expand and simplify an expression using the FOIL method. The second problem requires the proper use of the quadratic formula to solve an expression....

A student performs their version of the quadratic formula.

This is a lecture presentation on the quadratic formula extension, specifically focusing on solving equations with algebraic fractions. The speaker explains how to rearrange the equation into the form of ax^2+bx+c=0 and use the quadratic...

Before the method of completing the square was developed, only very limited types of quadratic equations could be solved. This method eliminated those limitations, allowing the solutions of any quadratic equation to be found. As...

This video is a lecture presentation on the quadratic formula. The presenter explains the form of a quadratic equation and identifies the values of a, b, and c for a given example. The quadratic formula is then introduced and explained...

This video explains how to solve quadratic equations either by factorizing or by using the quadratic formula. The instructor first describes how to factorize a quadratic equation using the sum and product method to convert it into double...

In this video, we learn how to solve quadratic equations with the quadratic formula. We examine one example where we have to simplify the radical, and a second example with a nonreal solution.
