Solution for 1/2x^2-16x=5 equation: 


x in (-oo:+oo)

(1/2)*x^2-(16*x) = 5 // - 5

(1/2)*x^2-(16*x)-5 = 0

(1/2)*x^2-16*x-5 = 0

1/2*x^2-16*x-5 = 0

DELTA = (-16)^2-(-5*1/2*4)

DELTA = 266

DELTA > 0

x = (266^(1/2)+16)/(1/2*2) or x = (16-266^(1/2))/(1/2*2)

x = 266^(1/2)+16 or x = 16-266^(1/2)

x in { 16-266^(1/2), 266^(1/2)+16 }
