x in (-oo:+oo)
1.24 = x^2-((x^1)/3) // - x^2-((x^1)/3)
(x^1)/3-x^2+1.24 = 0
x/3-x^2+1.24 = 0
1/3*x-x^2+1.24 = 0
DELTA = (1/3)^2-(-1*1.24*4)
DELTA = 5.07111111
DELTA > 0
x = (5.07111111^(1/2)-1/3)/(-1*2) or x = (-5.07111111^(1/2)-1/3)/(-1*2)
x = (5.07111111^(1/2)-1/3)/(-2) or x = (5.07111111^(1/2)+1/3)/2
x in { (5.07111111^(1/2)-1/3)/(-2), (5.07111111^(1/2)+1/3)/2 }
