Introduction to Quadratic Equations

The quadratic formula was originally developed by early Egyptians and Babylonians, most likely as a solution to figuring out the problems of space and area. Over the millennia, the basic quadratic equation has evolved to the format, that students are familiar with today.

In middle school algebra, students rarely study the quadratic formula in more than its basic form; however, after mastering the properties and applications of linear functions, focus on quadratics is the next natural step.

This module will briefly review the properties and applications of quadratics. You will also finish this course by developing your own concept map to illustrate your own personal understanding of the relationship between the concepts in this course. You will have the opportunity, if you choose, to practice using an easy-to-use, free software called FreeMind to build your concept map.

Finally, you will complete a review and reflection on your experience with blogging about Math and Algebra.

Module Eight Objectives

At the completion of this module, you will be able to:

• Define and describe a quadratic equation/function
• Demonstrate and explain the difference between a linear and quadratic equation
• Build a concept map that summarizes the major concepts covered in this course
