What is the GCF of -2xy and -9y

NNADVOKAT [17]

Answer:

$- y(2x + 9)$

Step-by-step explanation:

The GCF doesn't have to be a number. In this case, it is -y because both the -2xy and -9y share it. It's also easier when you take out a negative. Once you take the GCF out, your new expression should be:

$- y(2x + 9)$
