For this problem, we're being asked to factor the given polynomial by grouping.
00:04
So you always know you're going to do grouping when there's four terms.
00:08
So just like in any factoring problem, you should always start by looking for a greatest common factor throughout the entire thing.
00:13
But in this case, there is none.
00:15
So now we can actually do the grouping method.
00:17
So what we're going to do first is split the problem in half.
00:20
And we're going to factor out the greatest common factor from the first two terms, which in this case would be x squared.
00:27
So now we'll divide both terms by x squared, which is going to look.
00:30
Leave us with x minus 3...
