Which of the following formulas is not equal to

\int_{4}^{8} \frac{3 x + 1}{x^{2} - x - 6} d x

\int_{4}^{8} \frac{2}{x - 3} d x - \int_{4}^{8} \frac{1}{x + 2} d x

\int_{4}^{8} \frac{2}{x - 3} d x + \int_{4}^{8} \frac{1}{x + 2} d x

\int_{4}^{6} \frac{3 x + 1}{x^{2} - x - 6} d x + \int_{6}^{8} \frac{3 x + 1}{x^{2} - 6 - x} d x

\int_{8}^{4} \frac{- 1 - 3 x}{x^{2} - x - 6} d x
