Hi guys,

I have an exam tomorrow, for which I am prepared for except for the topic of inverse operator. I've been trying to learn this topic for the last few days, but I can't seem to. Can someone please explain how inverse operators work?

Also, could someone solve and explain to me in detail how to solve the following using inverse operator method: 4y'' - 3y' + 9y = 5x^2

Thank you for all the help in advance!
