Factor the GCF: 12x3y + 6x2y2 - 9xy3.

3xy

Step-by-step explanation:

coefficient: 12 6 - 9 The common factor is 3. Each can be evenly divided by 3

x: x^3 x^2 x

x: The common factor is x

y: y y^2 y^3

y: The common factor is y

The GCF is 3*x * y

If you want what is left over in the brackets, you will get

3xy (4x^2 + 2xy - 3y^2)

3xy (4x^2 + 2xy - 3y^2)
