laplace transform - Partial fraction for complex roots using the second order polynomial

(s2+s+1)(s2+4s+3)(s+1)



the answer has to be in a A(s+1)+Bs+C(s2+4s+3) form.
However i tried to solve it this way but end up with that there is no solution for this problem. For instance i get: A=1+A to solve for A which is false. Please help me i spent a lot of time solving this question with different ways and have no ideas left.
