Evaluate the limit LaTeX:  \displaystyle \lim_{x \to 8}\frac{2 x^{2} - 6 x - 80}{9 x^{2} - 69 x - 24}

The limit is an indeterminate form of the type LaTeX:  \displaystyle \frac{0}{0} . Using L'Hospitial's rule and then the evaluation theorem gives: LaTeX:   \lim_{x \to 8}\frac{2 x^{2} - 6 x - 80}{9 x^{2} - 69 x - 24} = \lim_{x \to 8}\frac{4 x - 6}{18 x - 69} = \frac{4 (8) - 6}{18 (8) - 69} = \frac{26}{75}
