Solve the inequality LaTeX:  \displaystyle \frac{5}{x^{2} - 4}<\frac{5}{x^{2} - x - 6}

Getting zero on one side and factoring gives LaTeX:  \displaystyle \frac{5}{\left(x - 2\right) \left(x + 2\right)} - \frac{5}{\left(x - 3\right) \left(x + 2\right)}< 0 . This gives the least common denominator as LaTeX:  \displaystyle \left(x - 3\right) \left(x - 2\right) \left(x + 2\right) . Building each fraction to get the common denominator gives LaTeX:  \displaystyle \frac{5 x - 15 - (5 x - 10)}{\left(x - 3\right) \left(x - 2\right) \left(x + 2\right)} < 0 . Simplifying gives LaTeX:  \displaystyle - \frac{5}{\left(x - 3\right) \left(x - 2\right) \left(x + 2\right)}<0 . The inequality can change signs at the zeros of the numerator, LaTeX:  \displaystyle \emptyset , or the zeros of the denominator LaTeX:  \displaystyle \left\{-2, 2, 3\right\} . Making a sign chart gives: This gives the solution LaTeX:  \displaystyle \left(-2, 2\right) \cup \left(3, \infty\right)
