the questions asks to determine inverse laplace transform of
The Attempt at a Solution
this can supposedly be done just using laplace transform tables so I am guessing i need to simplify that to something that's workable but i don't know how.
the solution is
e^(-4t) (t^2/2 - (2/3) t^3)
anyone can help in directing me how to simplify that equation before i use tables to inverse?
