All right, let's simplify this function.
00:04
So, 9 and 4 don't have a factor that factors out.
00:11
An x and x don't have, okay, so 4 doesn't have an x.
00:15
So we can't just easily simplify first.
00:19
Okay, so we have x squared.
00:21
And remember, we would split the x's.
00:24
But there is a 9 in the coefficient.
00:28
So we need to split that nine equally as well, right? and so nine split equally is three and three.
00:37
So we have three x and three x.
00:40
We have to do the same thing with four.
00:42
Split four equally...
