Solving Problems Using Quadratic Equations

Most problems can be solved using more than one method. A learning exercise includes just nine questions but many more ways to solve each. Scholars must graph, solve, and justify quadratic problems.

In need of a practice worksheet solving quadratic equations using the formula? Have no fear, we have one for you! This worksheet provides the formula at the top with 14 questions following using a variety of leading coefficients. 

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...

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.

Introducing square roots into the quadratic equation mix, Sal addresses the ways viewers might solve the problems, both correctly and incorrectly. The video is an integral step in not only Sal's algebra series but also in developing math...

Your algebra learners will pick up some solid algebra problem solving skills and a plan of approach for some typical types of word problems in this scripted worksheet that shows how to set up and organize each type of problem,...

Use word problems to teach systems of equations! The instructor in this video demonstrates how to solve a word problem using a system of equations and the elimination by subtraction method. She goes through each step, carefully...

Yes, it's a word problem but you have all the information you need to solve it. You have a formula, and they have given you a value to plug in. So get to it and write out the formula, plug in the value and solve this word problem.
