So you are at a level of DE's. So must know know how to do highschool algebra, right? that's basically all that you need (and to know how to minimanny differentiate).

Let y = a0 + a1x + a2*x² + ...

Replace this into the DE. Do the required derivatives.

From there is all and only highschool algebra.

Simplify (collect powers of xⁿ).

Surely you can take it from there!? If not, show your work and we will proceed.
