Solving simple transfer function I was hoping that you can help me understand how to find poles and zeros in this transfer function.

$$
H(s)=\frac{1}{(s-s_{\alpha1})(s-s_{\alpha2})}
$$

I know that this function does not have any zeros, because of the 1.

From the solutions I can see that the poles are $s_{\alpha1}=-1+j$ and $s_{\alpha2}=-1-j$ and to tell you the truth, I have no idea how to get solution for the poles.

I tried to solve it using quadratic equation, but the only thing I get is a big mess.

Thanks!!
Because $s-s_{\alpha1} = 0 $ and $s-s_{\alpha2} = 0 $ so poles: $s_1,s_2 = s_{\alpha1},s_{\alpha2} $ 
What numerical values you have for $s_{\alpha1},s_{\alpha2} $ are the What numerical values you are looking for.
