Okay, so we want to simplify our following.
00:04
So let's start by factoring each term.
00:06
From this term, we can factor out of two, and then we have an x squared minus 2x, and then minus 15.
00:13
Well, we can factor that into an x minus 5 and a x minus 3.
00:22
And now for this term, let's factor out a 5, and we have an x squared minus a 8x, and then minus 115, but we can factor that into a minus 5.
00:35
Actually, let's see, this is actually an 8x minus 15.
00:45
Is that a minus or a plus? it's minus...
