SUMMARY
The inverse Laplace transform of the function F(s)=(8s^2-4s+12)/(s(s^2+4)) is calculated to be f(t)=3-2 sin(2t)+5 cos(2t). The solution involves decomposing the function into partial fractions, identifying constants A, B, and C, and applying known Laplace transforms. The constants are determined as A=3, B=5, and C=-4, leading to the final expression for f(t).
