Solution for 4+1/3x-1/2x^2 equation: 


x in (-oo:+oo)

(1/3)*x-((1/2)*x^2)+4 = 0

(-1/2)*x^2+(1/3)*x+4 = 0

1/3*x-1/2*x^2+4 = 0

DELTA = (1/3)^2-(-1/2*4*4)

DELTA = 73/9

DELTA > 0

x = ((73/9)^(1/2)-1/3)/(-1/2*2) or x = (-(73/9)^(1/2)-1/3)/(-1/2*2)

x = 1/3-(73/9)^(1/2) or x = (73/9)^(1/2)+1/3

x in { 1/3-(73/9)^(1/2), (73/9)^(1/2)+1/3 }
