The Attempt at a Solution

I attempted the shifting method and also partial fraction method but efforts were fruitless

Show us what you got from those efforts because that approach will work.

 

[physicsnewb7]

which one?

You can use both concepts in finding the solution, but you should start with partial fractions to separate it into simpler pieces.
