$f (x) = x \ln (x - x)$

Step 1

Subtract $x$ from $x$ .

$\frac{d}{d x} [x \ln (0)]$

Step 2

Since $\ln (0)$ is constant with respect to $x$ , the derivative of $x \ln (0)$ with respect to $x$ is $\ln (0) \frac{d}{d x} [x]$ .

$\ln (0) \frac{d}{d x} [x]$

Step 3

The natural logarithm of zero is undefined.

Undefined
