I'm trying to generate exact real solutions to cubics and polynomials of higher degree, for example x^3+x^28x+1=0. I'd like for the solutions to be posted using purely real numbers. Instead, I get something like this:
{{x > (1/3) + 25/(3 (1/2 (101 + 3 I Sqrt[5811]))^(1/3)) +
1/3 (1/2 (101 + 3 I Sqrt[5811]))^(1/3)}, {x > (1/3) 
1/6 (1 + I Sqrt[3]) (1/2 (101 + 3 I Sqrt[5811]))^(1/3)  (
25 (1  I Sqrt[3]))/(
3 2^(2/3) (101 + 3 I Sqrt[5811])^(1/3))}, {x > (1/3) 
1/6 (1  I Sqrt[3]) (1/2 (101 + 3 I Sqrt[5811]))^(1/3)  (
25 (1 + I Sqrt[3]))/(3 2^(2/3) (101 + 3 I Sqrt[5811])^(1/3))}}
What commands would simplify this down to real numbers, if at all possible?
