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.

PREREQUISITES
  • Understanding of integral calculus
  • Familiarity with partial fraction decomposition

Evaluate the integral ∫ (3 + √x) / (x(3 + x)) dx

I've broken it up into ∫ [3 / x(3 + x)] dx + ∫ [ √x / (x(3 + x))] dx

And that's as far as I can get.

The first one is partial fractions. For the second one I suggest u=sqrt(x).
