The solution

You have entered [src]

   / 2          \
log\x  - 2*x + 2/

$$\log{\left(\left(x^{2} - 2 x\right) + 2 \right)}$$

log(x^2 - 2*x + 2)

Detail solution

Let $u = \left(x^{2} - 2 x\right) + 2$ .
The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(\left(x^{2} - 2 x\right) + 2\right)$ :
1. Differentiate $\left(x^{2} - 2 x\right) + 2$ term by term:
  1. Differentiate $x^{2} - 2 x$ term by term:
    1. Apply the power rule: $x^{2}$ goes to $2 x$
    2. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x$ goes to $1$
      So, the result is: $-2$
    The result is: $2 x - 2$
  2. The derivative of the constant $2$ is zero.
  The result is: $2 x - 2$
The result of the chain rule is:

$\frac{2 x - 2}{\left(x^{2} - 2 x\right) + 2}$
Now simplify:

$\frac{2 \left(x - 1\right)}{x^{2} - 2 x + 2}$

The answer is:

$\frac{2 \left(x - 1\right)}{x^{2} - 2 x + 2}$
