So I assume you haven't done second or higher order differential equations at all yet? Because usually these kind of problems are tackled before inhomogeneous differential equations show up.

I saw that this month, but I don't know how to solve this problem. What do I do with this y that you provided?

differentiate it and then plug it back into your DE, solve for \(\lambda\)

You can use method of undetermined coefficients.
