The GCF is 3.
The GCF of 6x and 9x is 3x
(3x - 2y)(9x^2 + 6xy + 4y^2)
The GCF is 9.
3x
The GCF is 3.
9x-6xy = 3
The GCF of 6x and 9x is 3x
(3x - 2y)(9x^2 + 6xy + 4y^2)
The GCF is 3.
Type your answer here... 81
The GCF is 9.
3X
3y(3x - 2y)(9x^2 + 6xy + 4y^2)
3x
9x^2-6xy+y^2 = (y-3x)^2 (y-3x)^2-81 -> ((y-3x)+9)((y-3x)-9)
You don't need to factor that; you can add them together, since they have the same variable.However, assuming you might mean 81x squared + 9x, you can take out the common factor, which is 9x.
