And here's your shmoop du jour.

00:06

Simplify the expression: colon... negative sign... closed parenthesis.

00:11

Very good. Now... simplify this expression:

00:15

2(x - 3) - 3(y + 2).

00:19

And here are the potential answers...

00:21

And yeah, hit pause, try it yourself first.

00:25

OK, this question is asking, "can we distribute factors?"

00:29

It would be rude not to answer, wouldn't it?

00:31

Remember the formula for distribution of terms? It looks like this:

00:36

Then just follow the map...

00:39

...and we get 2 times x minus 6 minus 3 times y minus 6.

00:45

Tricky thing there -- that 3 is NEGATIVE so don't forget to bring along the negative sign.

00:52

This expression simplifies to 2x - 3y - 12...

00:56

...and the answer is C. Easy peasy. See? No reason for a frowny face.
