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...

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):

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 (kendricklamar2014):
Yes, so it makes:\[(3x^2)+(8x+7x)\]
OpenStudy (i_love_my_nieces):
ok hold on
