Solution for (1/3x^2)-(1/18x)-(5/18)=0 equation: 


x in (-oo:+oo)

(1/3)*x^2-((1/18)*x)-(5/18) = 0

(1/3)*x^2+(-1/18)*x-5/18 = 0

1/3*x^2-1/18*x-5/18 = 0

DELTA = (-1/18)^2-(-5/18*1/3*4)

DELTA = 121/324

DELTA > 0

x = ((121/324)^(1/2)+1/18)/(1/3*2) or x = (1/18-(121/324)^(1/2))/(1/3*2)

x = 1 or x = -5/6

x in { -5/6, 1 }
