You can put this solution on YOUR website!
3X4Y^3-5Y-2X-3Y^3+5Y
3X4Y^3-2X-3Y^3
--------------------------------------
UNLESS YOU MEANT TO SEPARATE THE 3X & THE 4Y^3 --- THEN YOU HAVE WITH A + OR A -
3X+4Y^3-2X-3Y^3
X+Y^3
----------------------------------
OR
3X-4Y^3-2X-3Y^3
X-7Y^3

Hi Lackinmath,
This has been posted a few times. I really think that the book or worksheet that this came from has a type-o. I think there should be either a + or - between the x and the 4 in the first set of parentheses.
(3x4y^3-5y)-(2x+3y^3-5y)
As written all you can do is:
%283%2A4xy%5E3-5y%29-%282x%2B3y%5E3-5y%29
12xy%5E3-5y-2x-3y%5E3%2B5y
12xy%5E3-5y%2B5y-2x-3y%5E3
12xy%5E3-2x-3y%5E3
If there were a + between the x and the 4:
%283x%2B4y%5E3-5y%29-%282x%2B3y%5E3-5y%29
3x-2x%2B4y%5E3-3y%5E3-5y%2B5y
x%2By%5E3
Do you see why I think there is a type-o in your book or worksheet?
Happy Calculating, Lackinmath!!!!
