Book Problem 19 Consider the indefinite integral $\int \frac{4x^2 + 9x - 5}{x^3 + 2x^2} dx$. Using the partial fraction method, the integrand decomposes into the form $\frac{A}{x} + \frac{B}{x^2} + \frac{C}{x + 2}$ where $A = \frac{23}{4}$, $B = -\frac{5}{2}$ and $C = -\frac{7}{4}$. Integrating term by term, we obtain that $\int \frac{4x^2 + 9x - 5}{x^3 + 2x^2} dx = \text{ } + C$
