Okay, we've been given this fraction and we want to put it into partial fraction form.
00:05
First thing we're going to do is put, well, final factors.
00:10
So you can see that this is, well, very obviously going to be x squared plus three.
00:15
You've got xxx5 plus three.
00:18
So we're going to have a over x plus b over x squared.
00:35
Plus three.
00:38
So we've got a slight little problem.
00:42
Obviously, we're going to be timesing our a by x squared plus three and r b by x.
00:51
But that means that there's no way a would have to be zero then, which is what we don't want, because there's no way to get the x squared to count from.
01:02
We don't have any x squared...
