The GCF is 2x.

The greatest common factor of 4xy and -6xy is 2xy. To find the greatest common factor, we first factor out the numbers 4 and -6 to get 2(2xy) and -2(3xy). The greatest common factor is the highest common factor that divides both terms evenly, which in this case is 2xy.
Since 4xy2 is a factor of 20x2y4, it is automatically the GCF.
It stays the same because it does not have any common terms. A: 6y-4xy
The difference of cubes has a formula. (4x - y)(16x2 + 4xy + y2)
