LOL, graphic calculator....
6x^3 - x^2 - 13x + 8 = 0
-> 6x^3 - x^2 - 5x - 8x + 8 = 0
-> x ( 6x^2 - x - 5) - 8 (x - 1) = 0
-> x (6x + 5) (x - 1) - 8 (x - 1) = 0
-> (x-1) (6x^2 + 5x - 8) = 0
And I am sure you can solve that now, right?!
x = 1, (-5+-(25+4*8*6)^(0.5))/12
SUCH a long way of doing it [sm=tongue_smile.gif]
just factor it out and then use quad formula to get roots. <3 easy math
