Okay, so for this question we are subtracting two polynomials.
00:05
Now you'll notice that there are these coefficients in front of these polynomials that we can distribute to each of the terms.
00:14
And for this minus 6, we're going to distribute that negative sign so that we can turn this into an addition problem as well.
00:19
All right, so let's get started.
00:21
So we have 9 times y squared.
00:23
So it's going to give us 9 y squared.
00:27
And then we have 9 times negative 3y, which is going to give us minus 27 y.
00:36
Then we have 9 times 4, which is going to give us positive 36.
00:41
Okay, and then we'll do the second one.
00:44
We're going to add.
00:45
So we have negative 6 times 1.
00:48
That's just going to give us minus 6 over here.
00:51
And then we have negative 6 times negative y squared...
