Sorry, I should be able to do this but I am really frustrated right now and this is just a small part of a larger problem (I am so used to providing exponential solutions I forgot all about method of undetermined coefficients)
the problem is
trying to solve for H obviously
thanks,

P.S. I know to solve for the homogeneous solution first i.e. set LHS=0... (solution should be of the form t^2) I get hung up trying to deal with the constant on the RHS
