3xy - 3xy = 0

3xy
OK, say you have a variable like X. 3X 3 is the variable X's coefficient
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.

3xy + 3y2 = 3y (x + y)
3xy -- 3 is the coefficient of the variables x and y All these are being multiplied -- 3 times x times y Definition of coefficient -- A numerical value multiplied by a variable. Numerical values are not only whole numbers, but can be fractions (rational numbers), negative numbers, irrational numbers and imaginary numbers.
3xy - 3xy = 0
-3xy
It is x and y that are the unknown variables
3xy
(x + 6y)(x - 3y)
no
It is the same as: 12y^2 -3xy
(x - 4y)(x + y)
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
