 HW Helper Thanks P: 946 You need to start with a particular solution ($Cx^2/2$ will suffice, but if you expect your solution to have certain symmetry properties then it might be worth looking for a particular solution which shares those properties) and then add complementary functions to satisfy the boundary conditions.
