1. ## Cancelling down

I have

( 6n - 3n^3 ) / ( 2n^3 + 4n^2 )

Can someone show me how to cancel this down?

I got 6-3n^2 / 2n^2+4n

But I think it might be wrong

Well i think you're right. I might be missing something, but i cant see a way how it can be cancelled down any further.

Agreed.

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.
