Evaluate the following integrals:

To Find :

Now, let x - 3 be written as (2x + 3) - and split

Therefore ,

=

= -

Now solving,

Let = u dx =

Thus,becomes

Now , = = ) =

=

Now solving,

can be written as

i.e,

let = 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

Hence ,

= - = log |x + +|+C
