Answer: GCF = 3xy
Step-by-step explanation:
The coefficients are -18, -9, and 3. The GCF of those values is 3 because it's the largest factor in common to each.
- -18 = -6*3
- -9 = -3*3
- 3 = 3*1
The GCF of the x terms is simply x. Take note the smallest exponent for the x terms is 1. The GCF of the y terms is the same idea. Therefore the GCF of the y terms is y.
The GCF pieces are 3, x, and y. All together the GCF is 3xy.
