Solve the eq: z⁸ + 4z⁶ - 10z⁴ + 4z² + 1 = 0

Solve the eq: 4z¹¹ + 4z¹⁰ - 21z⁹ - 21z⁸ + 17z⁷ + 17z⁶ + 17z⁵ + 17z⁴ - 21z³ - 21z² + 4z + 4 = 0

Are those simultaneous equations ?

or different problems ? Is Z a complex number ?

Please clarify your problem. or send a screen shot of the source where you got the problem.

Yes, those solutions are complex.

Both the equations are different.
