Since this concept is in your text book then I believe it might be coming out in your exam, so I decided to make one video to discuss about it.
Hope you can understand it, quite hard to explain as well.

This video I will show two different method of solving this question:
1) Using Substitution Method
2) Partial Fraction Method.

Hope you find it helpful for you.
