##### Chapter 2 / Problem of Section 2.6 Q28

Hi there, I think there might be some problem with Q28. After I found the integrating factor and then solve for the solution, it's impossible to find the solution of my h(y) in this case (see the last line of my writing).

So in this case, I think there might be some problem with the factor that I circled in white.

Any help would be appreciated.

Yeah, I didn't do the partial fraction decomposition correctly, but the step after that is correct.
I still got the same answer again and again, but not the given one in the lecture slides:(

For another question, I've calculated this problem by using another method, which I think it makes sense,
but when I compared it to the slides, this is completely wrong, can somebody help me with it?

Any help would be appreciated.
