Help with polynomials

OpenStudy (misty1212):

hi!!

OpenStudy (misty1212):

what are you doing with them?

OpenStudy (i_love_my_nieces):

OpenStudy (i_love_my_nieces):

Simplify the polynomial.

OpenStudy (i_love_my_nieces):

@misty1212

OpenStudy (anonymous):

this is called "combine like terms"

OpenStudy (anonymous):

\[-4x+6x^2+5x\] the like terms are \(5x\) and \(-4x\)

OpenStudy (misty1212):

you got that? all you need is \(5x-4x\) right?

OpenStudy (i_love_my_nieces):

Do you guys not see the answer choices?

OpenStudy (i_love_my_nieces):

Y'all have me more confused...

OpenStudy (misty1212):

ok lets try this what is \(5-4\)?

OpenStudy (i_love_my_nieces):

1

OpenStudy (i_love_my_nieces):

Sorry I had to go somewhere @misty1212

@KendrickLamar2014

OpenStudy (kendricklamar2014):

1. Combine like Terms:\[(6x^2)+(-4x+5x)\]

OpenStudy (kendricklamar2014):

Which equals:\[6x^2+x\]

OpenStudy (kendricklamar2014):

Answer: Choice D

OpenStudy (i_love_my_nieces):

That is what I thought!! 3 more?

OpenStudy (kendricklamar2014):

Sure...

OpenStudy (i_love_my_nieces):

OpenStudy (i_love_my_nieces):

there

OpenStudy (kendricklamar2014):

Do you know what to do 1st?

OpenStudy (kendricklamar2014):

@I_love_my_nieces

OpenStudy (i_love_my_nieces):

Um, you find the like terms?

OpenStudy (kendricklamar2014):

I think u mean Combine Like Terms :P

OpenStudy (i_love_my_nieces):

Yeah :) lol

OpenStudy (kendricklamar2014):

Ok so we Combine Like Terms:\[(a^2+ -3a^2) + (5a)\]

OpenStudy (kendricklamar2014):

Which equals:\[-2a^2+5a\]

OpenStudy (kendricklamar2014):

Answer: Choice B

OpenStudy (i_love_my_nieces):

OpenStudy (i_love_my_nieces):

there

OpenStudy (i_love_my_nieces):

first combine like terms

OpenStudy (kendricklamar2014):

Yes, so it makes:\[(3x^2)+(8x+7x)\]

OpenStudy (i_love_my_nieces):

ok hold on

OpenStudy (kendricklamar2014):

Ok

OpenStudy (i_love_my_nieces):

Ok, I'm back

OpenStudy (i_love_my_nieces):

So, A?

OpenStudy (kendricklamar2014):

A is Correct

OpenStudy (i_love_my_nieces):

Okay, one more?

OpenStudy (kendricklamar2014):

:)

OpenStudy (i_love_my_nieces):

OpenStudy (i_love_my_nieces):

there

OpenStudy (kendricklamar2014):

Can you try to figure it out by yourself?

OpenStudy (kendricklamar2014):

@I_love_my_nieces

OpenStudy (i_love_my_nieces):

16?

OpenStudy (i_love_my_nieces):

@KendrickLamar2014

OpenStudy (kendricklamar2014):

Correct

OpenStudy (i_love_my_nieces):

Okay!
