How Do You Find the Impulse Response h(t) for a Differential Equation System?

[yoyo]

can someone show me how to find the impulse response h(t)?

questions: Determine the impulse response h(t) for the system characterized by the differential equation
y(2)(t) + 2 y(1)(t) + 17 y(t) = x(2)(t) + 5 x(1)(t) + 18 x(t)

thanks

How about taking the Laplace transform, solving for y/x, and then transforming back?
