problem. What's the common thread or unit between

all four of these elements? Ahh well, there we've already given you a hint.

Yeah the number 4 part of it. What else?

X. Okay so there's a 4x common to all of these

and we can factor it out to make life oh so much simpler.

We now have an equation that looks like this: 4x times the quantity xy

plus 4y plus 3x plus 12 we have an equation here

a very common form. We can factor this down to the

quantity X plus 4 times the quantity y plus 3.

Here we go. So boom! The answer is B.
