I don't think that is possible then... I mean without the calculators and stuff.

-1 is not the correct answer because if you test it instead of x the answer is 2 equals 0 and guys x is supposed to have more than 1 value!!!

It's cubic. There are 3 solutions.

Rough numerical approximations are (two of them are even complex):
Solution 1: 2.157298106+1.305151526*I
Solution 2: -.3145962123
Solution 3: 2.157298106-1.305151526*I

If you would like the answer to be different, perhaps you could ask a different question?
