Best ResponseYou've already chosen the best response.1Hmm.. One more.. Can you see the negative signs?

Best ResponseYou've already chosen the best response.1Yup! So, take out the common factor and group the rest of the terms. You'll get this: \[2k  k^3  3k^2\]\[=k(2+ k^2 + 3k)\]Rearrange the terms a bit: \[ = k (k^2+3k+2)\] From this, we can see that the 2nd one is nowhere near to the answer.
