Solution for -1/2x^2-11x-4=0 equation: 


x in (-oo:+oo)

(-1/2)*x^2-(11*x)-4 = 0

(-1/2)*x^2-11*x-4 = 0

-1/2*x^2-11*x-4 = 0

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

DELTA = 113

DELTA > 0

x = (113^(1/2)+11)/(-1/2*2) or x = (11-113^(1/2))/(-1/2*2)

x = -(113^(1/2)+11) or x = 113^(1/2)-11

x in { -(113^(1/2)+11), 113^(1/2)-11 }
