Homework Statement
f"(t)-f'(t)-2f(t)=12H0(t-3), f(0)=f'(0)=0
relevant equations, are the laplace transform equations..
H0(t-a)=e-as/s
The Attempt at a Solution
LT:s2F(s)-sF(s)-2F(s)=12e-3s/s
=>F(s)=12e-3s/s(s+1)(s-2)
ok now from here, I am lost, i can't do partial fractions can I? and i need to solve for f(t) which is inverse laplace of F(s), please can someone help me out, because I am not sure if can just take the inv laplace of that. please.
