Step 1 :

Find $\"\"$ .

Factorize the denominator of the integrand.

$\"\"$

By using partial fraction decomposition, find the partial fractions of the integrand.

The integrand is $\"\"$ .

$\"\"$

Equate x coefficients on each side.

$\"\"$ (1)

Equate constant terms on each side.

$\"\"$ (2)

Multiply equation (1) by 2, then subtract the equation from equation (2).

$\"\"$

Substitute $\"\"$ in equation (1).

$\"\"$

Substitute the values $\"\"$ and $\"\"$ in $\"\"$ .

Then the integrand is $\"\"$ .

$\"\"$

Apply formula : $\"\"$ .

$\"\"$

Thus, $\"\"$ .
