Question

\[\lim_{x \to 2} \left( \frac{1}{x - 2} - \frac{2}{x^2 - 2x} \right)\]

Solution

\[\lim_{x \to 2} \left[ \frac{1}{x - 2} - \frac{2}{x^2 - 2x} \right]\]
\[ = \lim_{x \to 2} \left[ \frac{1}{x - 2} - \frac{2}{x\left( x - 2 \right)} \right]\]
\[ = \lim_{x \to 2} \left[ \frac{x - 2}{x\left( x - 2 \right)} \right]\]
\[ = \lim_{x \to 2} \left[ \frac{1}{x} \right]\]
\[ = \frac{1}{2}\]
