Evaluate the limit LaTeX:  \displaystyle \lim_{x \to 1}\frac{3 x^{2} - 30 x + 27}{- 5 x^{2} + 9 x - 4}

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 1}\frac{3 x^{2} - 30 x + 27}{- 5 x^{2} + 9 x - 4} = \lim_{x \to 1}\frac{6 x - 30}{9 - 10 x} = \frac{6 (1) - 30}{9 - 10 (1)} = 24
