Evaluate the following integrals:

To Find :

Now, can be written as

i.e,

Here , let x + = y dx = dy

Therefore, can be written as

Formula Used: = log |x +|+ C

Since is of the form with change in variable.

= log |y +|+ C

= log |y +|+ C

Since , x + = y and dx = dy

= log |(x + ) +|+C

Therefore,

= log |x + +|+C
