@LaronJaxon , we have
$$3xy + 2x – 18y – 12$$
We need to factor this, then we'll be able to tell the correct answer
Notice the first two terms, there is x in both, take x common from both the terms, and write what do you get?

2+3y?

saranya · Answer

3xy + 2x – 18y – 12
x(3y+2) - 6(3y+2)
(3y+2)(x-6)
2+3y is a factor of 3xy + 2x – 18y – 12
