f(x)=x^3-3x/x^2

Change it to this:

f(x) = x3 - 3x*x-2

The only hard part is 3x*x-2, while x3 becomes 3x2. I'd assuming you using the product rule for 3x*x-2, I think.
When you like a flower, you just pluck it out.
But when you love a flower, you water it daily.
The one who understands this, understands life.

- That's the difference between I like you and I love you.
