Simplify (-24x^3+18x+6)/(6x+3)
-4x^2+2x-2
4x^2-2x-2
4x^2+2-2
-4x^2+2x+2
I need a bit help on this. I don't know how to do it. I think the first step is divide 18x+6 with 6x+3 and 6x+3 divide by 6x+3.
Am I on the right track? Please help
know the answers to the full connexus test?
Dividing just part of the numerator won't get you very far.
In cases like this, your best bet is to look for common factors. The denominator is very simple, so you should look for a factor of (2x+1) in the numerator.
(-24x^3+18x+6) = -6(4x^3-3x-1) = -6(x-1)(2x+1)^2
so now your expression becomes
-6(x-1)(2x+1)^2 / 3(2x+1) = -2(x-1)(2x+1) = -4x^2+2x+2
2k people saw this and it was posted In 2019 and yet nobody had the answers?....
tell em lmaoo
does some one have the answers to the whole test
do you guys have the test answers?
plz help with the answers plz
I’ll post them when I finish it.
The slurp can you please post the answers.

If you are still stuck, I would recommend using Demos or the Symbolab calculators—especially the latter. Hope this helps any future 7th grade Math students!
