About This Lesson
http://www.freemathvideos.com In this video tutorial I will show you how to factor an expression by grouping. Grouping is a factoring technique used when you have an expression with four terms. What we do is split the first two and last two terms and factor the GCF out of both. We then look at what the two terms share and factor that term out. Our final result will be two binomials multiplied by each other.
