Factoring Stuff Out (a.k.a. "distrubution in reverse"")
Instead of taking a problem like 2(x-3) and distributing it to 2x-6, we're going to do the exact opposite: start with 2x-6 and break it up into 2(x-3) by pulling out common factors. Seem like a waste? It's a necessary skill that you'll see throughout your math career, and it's a great lead-in for the more difficult type of factoring with two sets of parentheses, coming up in the next videos.
