I'm meant to find the particular solution to the differential equation

y'(t)+(-2t-8)*y(t)=131t-2t

^{3}

, which is in the form

I know that I can find the solution with the formula .

I have inserted P(t) (antiderivative of p(t)) and q(t) in the formula:

However, I do not know how to approach the integration of e

^{P(T)}*q(t). Does anyone have any advice?Thank you.
