2*x - 1
$$\frac{3 x}{2 x - 1}$$
(3*x)/(2*x - 1)
Detail solution
  1. Apply the quotient rule, which is:

    and .

    To find :

    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:

    To find :

    1. Differentiate term by term:

      1. The derivative of the constant is zero.

      2. 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:

      The result is:

    Now plug in to the quotient rule:


The answer is:

------- - ----------
2*x - 1            2
          (2*x - 1) 
$$- \frac{6 x}{\left(2 x - 1\right)^{2}} + \frac{3}{2 x - 1}$$
The second derivative [src]

12*|-1 + --------|
   \     -1 + 2*x/
------------------
             2    
   (-1 + 2*x)     
$$\frac{12 \left(\frac{2 x}{2 x - 1} - 1\right)}{\left(2 x - 1\right)^{2}}$$
The third derivative [src]
   /      2*x   \
72*|1 - --------|
   \    -1 + 2*x/
-----------------
             3   
   (-1 + 2*x)    
$$\frac{72 \left(- \frac{2 x}{2 x - 1} + 1\right)}{\left(2 x - 1\right)^{3}}$$
