You have entered [src]
            ___
(2*x - 3)*\/ x 
$$\sqrt{x} \left(2 x - 3\right)$$
(2*x - 3)*sqrt(x)
Detail solution
  1. Apply the product rule:

    ; to find :

    1. Differentiate term by term:

      1. The derivative of a constant times a function is the constant times the derivative of the function.

        1. Apply the power rule: goes to

        So, the result is:

      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:

The first derivative [src]
    ___   2*x - 3
2*\/ x  + -------
              ___
          2*\/ x 
$$2 \sqrt{x} + \frac{2 x - 3}{2 \sqrt{x}}$$
The second derivative [src]
    -3 + 2*x
2 - --------
      4*x   
------------
     ___    
   \/ x     
$$\frac{2 - \frac{2 x - 3}{4 x}}{\sqrt{x}}$$
The third derivative [src]
  /     -3 + 2*x\
3*|-4 + --------|
  \        x    /
-----------------
         3/2     
      8*x        
$$\frac{3 \left(-4 + \frac{2 x - 3}{x}\right)}{8 x^{\frac{3}{2}}}$$
