Solution for 1/2x^2-1/4x-3/2=0 equation: 


x in (-oo:+oo)

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

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

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

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

DELTA = 49/16

DELTA > 0

x = ((49/16)^(1/2)+1/4)/(1/2*2) or x = (1/4-(49/16)^(1/2))/(1/2*2)

x = 2 or x = -3/2

x in { -3/2, 2 }
