SUMMARY
The integral ∫ (3 + √x) / (x(3 + x)) dx can be evaluated by breaking it into two parts: ∫ [3 / x(3 + x)] dx and ∫ [√x / (x(3 + x))] dx. The first part requires the use of partial fractions for simplification. For the second part, the substitution u = √x is recommended to facilitate integration.
