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
