............................................
1. Find the first derivative. (You will need the quotient rule.)
2. Set that = 0 and solve.
3. Find the second derivative. (Takes a little work.)
4. Try each solution into the second derivative.
  -- if it comes out (+), it's a min.
  -- if it comes out (-), it's a max.

I think you will get x = 0 (min),  x = 2 (max)
