Okay, so first let's set this up.
00:02
We have f of x, which is x to the fourth, minus 3x cubed, plus 6x squared, minus 3x plus 5, divided by d of x, which is x squared plus 1.
00:24
Okay, so first we have an x squared here and an x to the 4 here.
00:28
We want to multiply something by x squared to get x to the 4.
00:31
Fourth so we can subtract it out.
00:34
So that would probably be x squared.
00:36
And we want to put that in the x squared section.
00:39
X squared times x squared is x to the fourth.
00:42
And then we want to put a placeholder here so that we can make subtracting easier.
00:47
So we have zero x cubed here and then here x squared times one is x squared.
00:55
Okay, and we subtract x the fourth minus x the fourth is 0.
01:00
Negative 3x squared minus 0 is negative 3, sorry x cubed at 6x squared minus x squared is 5x squared...
