The first step when we're factoring polynomials should be to find a gcf, a greatest common factor.
00:07
In this problem, we notice that we have two terms.
00:10
This is one term, and this is another term.
00:14
And within those two terms, hopefully you can see that we have this 4x and this 2x, they have a common factor, meaning we can factor out a 2 and an x.
00:27
We also see that this 5x minus 1 is common in both of those.
00:33
So we're going to factor that out.
00:37
And again, we're only going to take out five of them.
00:39
Because remember, when you're doing a gcf, you always choose the smaller exponent.
00:43
That's why we only factored out an x to the first when we had a 2 and a 1...
