OK, so you have a general solution of the form:



and the initial conditions will allow you to determine and , which you appear to have done.

What would the complementry fuction be and paticular solution to work towards the solution of:

What are you asking here?

So using the initial conditions would give:





But then how do you solve these equations ?

from 1st,

by substituting from the above into the second.

So:





Assuming my algebra is right (check it, it appears to differ from what you are give by a sign here or there).
