Unless the final answer requires the numerator and denominator to be factorised.
And there's always the chance of a typo in the question ...... ( 12n - 3n^3 ) / ( 2n^3 + 4n^2 ) cancels down in perhaps a more 'expected' way .....
But that's rather a big typo to make. Think about it. Pressing 6 instead of 12... Also he got the same answer as one would expect for the problem given. So i doubt that there's a typo.

I was thinking more along the lines of a typo where the question was sourced.
But you're right - it's a long shot.
Probable moral of the story: A correct answer sometimes doesn't seem correct.
