The integrating factor is exp(x12).
The solution is yexp(x12) = ∫x12exp(x12) dx
I will leave the integration to you.
Sorry! You are correct...the integral is not so easy.
Integration by parts does seem to yield an answer.
I am not sure that the integral has an answer is closed form.
I apologize that I cannot be more help.
Please note: if when you review this problem in class, you get an answer, I would ask you to share that answer with me. Thanks.
