The solutions can be approximated to any degree of
accuracy by the use of technology. 

Two of the solutions are irrational real imaginary solutions

x≈-0.8138466122

x≈ 1.937109424

The others two are conjugate irrational complex imaginary solutions:

x≈-0.561631406 + 1.690009699i

x≈-0.561631406 - 1.690009699i
