Hello,

In[1]:= N[Solve[z + 5 (z^2 - 1) + 1 z^3 == 1, z]]
Out[1]= {{z -> 0.925423 + 0. I}, {z -> -4.47735 + 2.22045*10^-16 I}, {z 
-> -1.44807 - 4.44089*10^-16 I}}

In[2]:=[N[Solve[z + 5 (z^2 - 1) + 1 z^3 == 1, z] ] /.
  Complex[re_, im_ /; Abs[im] < 0.001] :> re
Out[2] = {{z -> 0.925423}, {z -> -4.47735}, {z -> -1.44807}}

HTH,
