Lesson Summary:

In this lesson, you will learn how to factor by using the sum of cubes. The instructor demonstrates how to use the abstract formula u cubed plus v cubed plus u plus v times u squared minus u times v plus v squared to factor a problem of 343 plus x to the fourth power. By factoring out an x and rewriting 343 as 7 cubed, the formula can be applied to solve the problem. This lesson provides a thorough explanation of the process involved in using the sum of cubes to factor, making it easy to understand and apply in practice.

Lesson Description:

Factoring by using a sum of cubes

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.
