SUMMARY
The forum discussion centers on the integration of the function \(\int \frac{1}{(x-1)(x+2)} \, dx\). The user attempted integration by letting \(u = x + 2\) and derived the result as \(\ln|x + 2| + C\). However, the correct approach involves using partial fraction decomposition to express the integrand as \(\frac{A}{x-1} + \frac{B}{x+2}\) before integrating. This method ensures accurate results for integrals of rational functions.
