Here's your shmoop du jour... brought to you by the makers of grey shmoopoun

00:07

Simplify: Quantity 5x plus 3xy plus 4y plus the quantity 4x minus 2xy minus 2y.

00:16

And here are the potential answers... oh what a mess.

00:21

OK so what is this question asking?

00:24

Well, we really just have to combine like terms.

00:27

Just don't tell the terms they... like each other. We don't want to be accused of betraying

00:32

confidences.

00:33

Since there's no multiplying or division at play here, we can really just ignore the

00:37

parentheses...

00:37

...and add everything that goes together... together.

00:42

5x and 4x give us 9x... 3xy MINUS 2xy gives us xy... and 4y MINUS 2y gives us 2y.

00:53

So... 9x plus xy plus 2y...

00:56

...and the answer is E.

00:57

As in, "Everyone deserves a little love."
