2xy
The difference of cubes has a formula. (4x - y)(16x2 + 4xy + y2)
Remove common factors. The common factor is 3x. Then since you must keep the expression constant you put in parentheses what you must multiply 3x by to get each of the original parts of the expression. So the answer must be 3x+3xy=3x(1+y).
3x2y - 4xy + 4x
x(y-10)+6(y-10) ^^^that's the first step, then: the x and 6 pair together, and one of the (y-10) leaves the expression so it becomes: (x+6)(y-10) this is referred to as Factoring by Grouping

The GCF is 4xy.
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)
4xy + 6xz When factorising algebraic expressions treat them just as ordinary numbers. Ascertain what the common factors are. The factors of 4xy are 2 x 2 x 'x' x y The factors of 6xz are 2 x 3 x 'x' x z The factors common to both expressions are 2 and 'x'. Therefore, 4xy + 6xz = 2x(2y + 3z)
