Question

Find a particular solution to the differential equation:

2y'' - 1y' - 1y = -1t^2 + 2t + 3exp(3t)

Answer 1

divide each term by 2 and then proceed as normal using undetermine coefficients or variation of parameters

Answer 2

Thanks. I already know to use either method. I'm just not sure about the answer

Answer 3

you can always use wolfram alpha if you want to check the final solution
