Factoring Sums and Differences of Cubes

Factoring Sums and Differences of Cubes. In this video, I use the formulas for factoring sums and differences of cubes. I factor two expressions using the formulas.

You should show how these formulas can be derived, far more interesting than just a given also less memory intensive

For anyone who is interested, multiply out:

1. (x+y)^3 =RHS

2. (x-y)^3 = RHS

Work from there; once one is derived other is very similar

Nice video some useful applications

@livehigh80 Was not intended to be a criticism just a suggestion, mechanical learning is ok, but always nice to see how\why formulas exist; helps for unfamiliar problems etc

@1878DJM In this guy's defense.. I think he was going for the educational factor. For example, I missed this lesson due to an absence, so I youtube-d this in order to learn how to do the problems assigned for homework. Origin stuff is something you do quickly before the lesson, or the next day which wastes further class time. Thank you for the upload!
