inverse laplace method for equation .....

Just doing some revision but im a little stuck on how to find the inverse laplace of 1/s(s-2)

 

[LeonhardEuler]

You can find it using partial fractions.

1/s(s-2)= A/s+ B/(s-2) for appropriate A and B- that's the "partial fractions" the eminent LeonhardEuler mentioned. One good way to solve for A and B is to multiply both sides by s(s-2) and then plug in simple values for s to get two equations for A and B.
