You have entered [src]
          ___
(x - 3)*\/ x 
$$\sqrt{x} \left(x - 3\right)$$
(x - 3)*sqrt(x)
Detail solution
  1. Apply the product rule:

    ; to find :

    1. Differentiate term by term:

      1. Apply the power rule: goes to

      2. The derivative of the constant is zero.

      The result is:

    ; to find :

    1. Apply the power rule: goes to

    The result is:

  2. Now simplify:


The answer is:
