All right, so we have x squared plus y minus two times the quantity x squared plus y plus two.
00:05
So we're going to distribute first the x squared and then the y and then the negative two.
00:12
So we have x squared times x squared that gives us an x to the fourth.
00:17
And then x squared x squared y gives us a plus x squared y.
00:22
So plus x squared y.
00:24
And then x squared times 2 gives us a plus 2 x squared.
00:30
Okay, and then the y distributes.
00:33
So y times x squared, well, that's a plus x squared y, and then the y times y, that's just a plus y squared.
00:42
And then y times two is a plus 2 y.
00:48
Okay, and then lastly the negative 2 distributes.
00:50
So if negative 2 times x squared is a negative 2 x squared.
00:57
Then negative 2 times y is a negative 2 y, and then negative 2 times negative 2 is a minus 4.
01:04
Okay, so then combining like terms, well, we only have the 1x to the 4th.
01:09
So we have an x to the 4th.
01:11
Okay, and now how about x cubed? we have any x cubes? i see no x cubes.
01:17
Okay, so what about, well, we have, let's take a look at the next term...
