I have been trying to solve this problem for hours and have looked at many examples, but I still can't solve it. It is a past exam question, so I don't know if there was an error or if I am just doing it wrong.
The problem says:
"Consider the ordinary differential equation
Using the Method of Undetermined Coefficients, find a particular solution of the inhomogeneous problem."
So I have tried to solve it using , but I can't get anything because the only result I get is , and no values for or . And would give instead of .
I would really appreciate it if someone could give me a hand. Thanks a lot!
