Question

Factor the GCF:

Answer 1

The greatest common factor (GCF) is the product of the greatest common factors of the numerical coefficients and the variables involving x and y. 
                           
                           -12(x^4)y - 9x³y² + 3x²y³
     
                            -3x²y(4x² + 3xy - y²)

Thus, the answer is letter A.
