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

    and .

    To find :

    1. Differentiate term by term:

      1. The derivative of the constant is zero.

      2. Apply the power rule: goes to

      The result is:

    To find :

    1. Differentiate term by term:

      1. The derivative of the constant is zero.

      2. Apply the power rule: goes to

      The result is:

    Now plug in to the quotient rule:


The answer is:

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

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