OpenStudy (danjs):

just add up like terms

OpenStudy (winsteria):

okayyy

OpenStudy (danjs):

you can see immediately that the first term is x^2

OpenStudy (danjs):

which leaves only one answer to choose

OpenStudy (winsteria):

C?

OpenStudy (winsteria):

Idk

OpenStudy (jhannybean):

\[(7y -5y) +(-x^2 ++3x+17x+2x^2)\]Simplify.

OpenStudy (danjs):

the first term is x^2, that is not C

OpenStudy (winsteria):

uhh

OpenStudy (jhannybean):

From what I posted, combine like terms.

OpenStudy (winsteria):

D?

OpenStudy (jhannybean):

Stop guessing first.

OpenStudy (jhannybean):

Tell me what \(2x^2-x^2\) equals.

OpenStudy (winsteria):

I don't know :/

OpenStudy (jhannybean):

What is 2-1.

OpenStudy (winsteria):

1

OpenStudy (jhannybean):

You're left with \(x^2\). Second set of like terms: \(-17x+3x\). what is -17+3?

OpenStudy (winsteria):

-14

OpenStudy (jhannybean):

Good, so you have \(x^2 -14x\) now. now we have \(7y -5y\). What is 7-5?

OpenStudy (winsteria):

2

OpenStudy (jhannybean):

There you go, now you have : \(x^2 -14x +2y\) Can you find your answer choice now?

OpenStudy (winsteria):

B? :)

OpenStudy (jhannybean):

YEs, good job.

OpenStudy (winsteria):

Thank you for your help, I understand it now :)

OpenStudy (jhannybean):
