Hey all.

I am having a lot of trouble finding particular solutions.

I have three problems:

A)

B)

C)

I am trying to find the particular solutions using the method of undetermined coefficients.

For A), I found the general solution to be

and the particular solution to be

For B), I found the general solution to be

and the particular solution to be

For C), I found the general solution to be

(everything in the parenthesis after e is what e is raised to.

and the particular solution to be

None of these check out. I am flustered and frustrated with this and don't know what else to do. PLEASE HELP!!!

Thank you
