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.

Sorry, here is the first image

Here is the second image

In the textbook, it is e^(2y). Maybe this one is correct.

If you found an integrating factor correctly there should be no problem to $h(y)$. There is a problem with your solution, not with the problem.

Both are correct
