Find the inverse Laplace transform of a. F(s) = se-6s/(s-2)(s2+2s+1) b. F(s) = e-12s/s3(s2+4)

Find f(t) if L(f)=s/(s^2+16)^2.

Express the inverse transform as an integral s(s+3)/[(s^2+4)(s^2+6s+10)]

Find inverse laplace transform of F(s)=(6s^3+120s^2 +806s+1884)/(s^2+10s+29)^2 please write detailed answer thanks in advance
