SOLUTION: Differentiate this function f(x) (x-2) / x^(2) I got: 1/x -2/x^(2) Then: x^(-1) -2x^(-2) Then differentiated: -1x^(-2) + 4x^(-3). My answer: -1/x^(2) + 4/x^(3) However

Question 936599: Differentiate this function f(x)
(x-2) / x^(2)
I got: 1/x -2/x^(2)
Then: x^(-1) -2x^(-2)
Then differentiated: -1x^(-2) + 4x^(-3).
My answer: -1/x^(2) + 4/x^(3)
However this was wrong. The answer in the book was: (4-x) / x^(3)
