Alright, so given an algebraic expression of 2x squared y cubed times 3x minus 4y squared minus 2x squared y cubed times 3x minus 4y minus 16x squared y to the fourth times 2y minus 3x.
00:26
So we're going to expand and simplify what we can.
00:28
So this is going to be 2x squared y cubed.
00:32
This is going to turn into 9x squared and then minus 12xy.
00:41
Actually, that's going to be 24xy.
00:45
So minus 24xy and then plus 16y squared.
00:50
This becomes minus, this would be 2, or 6x cubed y, 6x cubed y cubed, then plus 8x squared y to the 4th, minus 32x squared y to the 5th, minus 48.
01:15
48, this is 48x squared y, or 48x cubed y to the fourth.
01:25
It should be plus 48y cubed y to the fourth.
01:36
And then lastly, we should have, this should be 18x to the fourth y cubed, and then minus 48x cubed y to the fourth and then plus 32x squared y to the fifth and then everything else so after you're writing all these we want to combine what our like terms are plus 48x cubed y to the fourth so we have an x fourth y y cubed.

Do we have any more of those? nope...
