Finding the derivative of a fraction

How do I find the derivative of (4x+(x^3)-(x^4))/x^2, where x does not equal 0

I tried using the quotient rule but I can't seem to get the right answer. Can some please work this out step by step so I can see where I'm going wrong?

Thanks in advance

It would help if you showed us your working... we're not going to give you the full answer with working if we see no effort on your part.

Finding the derivative should now be a piece of cake :)

But then wouldn't you get (-4x^-2)+1-2x?

My textbook says the answer is (-2x^3+x^2-4)/x^2

Not sure how, this is my first time on this forum
