Integration problem

Question

Solve step by step.

Answer 1

The Integral function is .

Consider

Apply derivative on both side

 

Consider

Compare the coefficient of u.

A + B = 0

B = -A

Compare the constants.

-3A = 1

A = -1/3

There B = -A = 1/3

 

Then

  (Properties of Logarithmic Function ln(a/b) = ln(a) - ln(b))

Therefore .
