Find the limit of the given function

Find the value of the following limit.

    \[ \lim_{x \to 2} \frac{3x^2 + 2x - 16}{x^2 - x - 2}. \]


We apply L’Hopital’s rule,

    \begin{align*}  \lim_{x \to 2} \frac{3x^2+2x-16}{x^2-x-2} &= \lim_{x \to 2} \frac{6x + 2}{2x-1} \\[9pt]  &= \frac{14}{3}. \end{align*}

Since this limit exists, the application of L’Hopital’s was justified.
