my answer is y = c1 + c2(x^2) + (e^x)(x^2 + 4x) i just need to double check this answer.

your COMPIMENTARY solution is CORRECT.
your PARTICULAR solution is INCORRECT.
y_comp = c1 + c2(x^2)
y_part = x^2e^x
so general solution is:
y = c1 + c2(x^2) + x^2e^x
note: Like doug said above, you can always check your answer by plugging it into the original diff. e.q.

Take the 1'st and 2'nd derivatives and see what you get âº
(Right now, I'm a bit to drunk to feel safe with that âº)
