Solution for x^2-1/2-11*x=11 equation: 


x in (-oo:+oo)

x^2-(11*x)-(1/2) = 11 // - 11

x^2-(11*x)-(1/2)-11 = 0

x^2-11*x-1/2-11 = 0

x^2-11*x-23/2 = 0

DELTA = (-11)^2-(-23/2*1*4)

DELTA = 167

DELTA > 0

x = (167^(1/2)+11)/(1*2) or x = (11-167^(1/2))/(1*2)

x = (167^(1/2)+11)/2 or x = (11-167^(1/2))/2

x in { (11-167^(1/2))/2, (167^(1/2)+11)/2 }
