1, 3, x, y, 3x, 3y, and xy are the factors of the expression 3xy
2x^2y^3(4x^2 - 3xy + 1)
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
78 + yz = yz + 78
This illustrates the associative property.

3xy - 3xy = 0

3xy
18x3y5 + 9xy3 - 3xy = 3xy(6x2y4 + 3y2 - 1)
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20

3xy and 2xy. You can see that 3xy and 2xy have something in common with each other. They both have xy and the end of them. Hope this helped.
