उत्तर

\[\lim_{x \to 3} \left[ \frac{1}{x - 3} - \frac{2}{x^2 - 4x + 3} \right]\]
\[ = \lim_{x \to 3} \left[ \frac{1}{x - 3} - \frac{2}{x^2 - 3x - x + 3} \right]\]
\[ = \lim_{x \to 3} \left[ \frac{1}{x - 3} - \frac{2}{x\left( x - 3 \right) - 1\left( x - 3 \right)} \right]\]
\[ = \lim_{x \to 3} \left[ \frac{1}{x - 3} - \frac{2}{\left( x - 1 \right)\left( x - 3 \right)} \right]\]
\[ = \lim_{x \to 3} \left[ \frac{x - 1 - 2}{\left( x - 3 \right)\left( x - 1 \right)} \right]\]
\[ = \lim_{x \to 3} \left[ \frac{1}{x - 1} \right]\]
\[ = \frac{1}{3 - 1}\]
\[ = \frac{1}{2}\]
