Hey Guyz, Does the equation "imhereyeah" posted solves with 3 values of x? or 1 only?

Yes. Note that the "a" and "b" in that reply are derived from cube roots. So "a" and "b" each have 3 possible (complex) values giving a total of 9 combinations in the solution (though at most 3 will be distinct).
