Consider the indefinite integral $\int \frac{4x^3 + 9x^2 + 8x + 24}{x^4 + 4x^2} dx$. The integrand has partial fractions decomposition $\frac{a}{x^2} + \frac{b}{x} + \frac{cx + d}{x^2 + 4}$ where a = b = c = d = Integrating term by term, and using K for the constant of integration, we obtain that $\int \frac{4x^3 + 9x^2 + 8x + 24}{x^4 + 4x^2} dx = $
