Answer:
-6 (x + 3y)
Step-by-step explanation:
You can't factor out any variables in this case so you should look towards factoring out a number
To fully factor, you find the greatest common factor between terms and extract that, placing it on the outside of the parenthesis.
So you rewrite -18y as -6 times 3y and rewrite -6x as -6 times x.
