after solving a long diff question i got 0.5*u(t+1)-0.5*u(t-1) where u(t) is a step function for t>=0 its 1 and t<0 its 0 my expression looks pretty finite to me how to continue??

Continue how, it looks satisfactory to me (at least as a function definition). Though I would be wary of this as a solution of a differential equation as it has no derivative in the conventional sense at $\displaystyle t=\pm 1$. CB
Could you furnish the original question? It appears the original DE is non-homogeneous with the forcing term involving delta functions?
