Lesson Summary:

In this lesson, you will learn how to find the x and y intercepts of a quadratic equation. To find the y intercept, substitute 0 for x and solve for y. To find the x intercepts, substitute 0 for y and factor the equation. Three different factoring techniques, including using a box, taking out the leading term, and factoring by grouping, are discussed in detail to help you solve for the x intercepts, roots or solutions of the given equation.

Lesson Description:

How to factor an equation to find the x intercepts of the given equation

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.

    The instructor demonstrates how to find the y-intercept of a quadratic equation, as well as three different techniques that can be used to factor the equation. Although the three different techniques for factoring are demonstrated clearly, he does not follow through with actually finding the x-intercepts.
