Your code is hard to read and full of syntax errors. For example Sqrt[[Rho]] can't be correct. As far as the final answer you show in Out[1] then you simply use N to convert it to numerical values.

     N[%]
     {{x -> -0.486389}, {x -> -0.701874 - 0.879697 I}, {x -> -0.701874 + 0.879697 I}, 
      {x -> 0.945068 - 0.854518 I}, {x ->  0.945068 + 0.854518 I}}

These are the solutions. If you do not want to see the x there then write

    x /. %
    {-0.486389, -0.701874 - 0.879697 I, -0.701874 + 0.879697 I, 0.945068 - 0.854518 I, 0.945068 + 0.854518 I}
