Time for your daily dose of Shmoop...this won't hurt a bit.

00:06

Factor 4x squared y plus

00:08

16xy plus 12x squared plus 48x

00:12

And here are the potential answers...

00:18

Okay we have ourselves another factoring

00:20

problem. What's the common thread or unit between

00:23

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

00:28

Yeah the number 4 part of it. What else?

00:31

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

00:36

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

00:39

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

00:44

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

00:48

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

00:52

quantity X plus 4 times the quantity y plus 3.

00:56

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