The question is : "Is there a way to make the solve block to answer : Find(x) is a complex number : -2.94 + 0.019i ?
Thanks in advance for your time and help.
Best Regards.

The wording in the help is not correct, though. What they mean instead of "complex" actually is "non-real". After all every real number also is a complex number!

So you may chose x:=-3+1i as a suitable guess.

 

And of course you should not use a constraint like -2.95 < x <2.90 because this implies that x would be a real number!

Its not necessary, but you may use something like -2.95 < Re(x) <2.90 or maybe Im(x)>0.
