Use method of substitution to evaluate integration x(x2+4) power 5 dx?


Integration using Method of Substitution

When evaluating the integral of x(x2 + 4)5 dx using the method of substitution, we follow these steps:

  • Select a substitution: Let u = x2 + 4. Then, du = 2x dx.
  • Express the integral in terms of u: Substituting u back into the integral gives us ∫x * u5 / 2 du.
  • Make the necessary adjustments: We need to rewrite the integral in terms of u and du. This involves replacing x and dx with expressions involving u and du.
  • Integrate with respect to u: The integral becomes (1/2) * ∫u5 du.
  • Integrate the new expression: Integrating u5 with respect to u gives u6 / 6.
  • Undo the substitution: Replace u with x2 + 4 to get the final result.


By following these steps, you can evaluate the given integral using the method of substitution.
