I find complex numbers very fascinating. But i don't understand something.
Why does a cubic equation have 3 answers instead of 6?
I know that there are 3 cube roots of a complex number, and the imaginary part of the complex number can be either positive or negative, so there should be 6 answers. Actually, if each side of the formula was independent of the other, there would be 3*4=12 answers.
I tried reading an article on the internet about galois theory, but it used a lot of jargon about fields and groups that i didnt understand.
Could somebody explain to me why there are only 3 roots, without all the jargon?
