Hello, I'm running into a little problem under Mathematica 5.0 but I'm sure people here will just take it as "too easy", but, well :) I just want the solutions of the equation : x^2 + x + 1 == 0 under their complex form. So, I type : Solve [x^2 + x + 1 == 0, x] But I unfortunately get : { { {x -> -(-1)^(1/3) }, { x -> (-1)^(2/3) } } } And I'd prefer to obtain the more "readable" form : -1/2 + I*1/2*Sqrt[3], -1/2 - I*1/2*Sqrt[3] that I would get under another system for instance. What special function should I call to get this form under Mathematica ? Thanks for any help -- Michaël Monerau -= JJG =-
