Hi, I have been working on this differential equation problem that is in the attachment i was wondering if someone could give me any advice to if this is the correct way of doing this and if i have the correct answer. sorry about the poor quality in scanning Thanks for your time Matt

I'm having a bit of a problem reading your handwriting, but it looks as though to find a particular solution of the ODE, you set , and then found P = 3/13, Q = 2/13, S = 7/8, and R = 3/4, which is right. But then for some reason in your final answer you switched it around to , which doesn't seem right. How I would do it: the particular solution of the ode, as you found, is , and the general solution to the homogeneous problem is , and so the general solution to the inhomogeneous problem is
