Bear with me here, I took DIFF EQ 3 semesters ago and laplace transforms have come up again in a new class and I need to help

Solve the following using Laplace transforms:

$\displaystyle x''+x'+x=1$ where x$\displaystyle '(0)= 0$ and $\displaystyle x(0)=0$

I get the equation down to $\displaystyle X(s)=X(s^2+s+1)=\dfrac 1s$

then $\displaystyle X(s) = \dfrac 1{s(s^2+s+1)}$

next I went to partial fractions: $\displaystyle \dfrac As + \dfrac{Bs+C}{(s^2+s+1)}$

then finding a common denominator and setting it equal to 1 i get $\displaystyle 1 = s^2(A+B) + s(A+C) + A$

Solving that I get $\displaystyle A=1,B=-1$ and $\displaystyle C=-1$

Plugging these back in I get $\displaystyle \dfrac 1s - \dfrac {s+1}{(s^2+s+1)}$

Now this is where I am stuck....I my table I cannot find a tranfer related to $\displaystyle \dfrac{s+1}{(s^2+s+1)}$ and I do not know how to manipulate it so I can use the tables.
