Solution for (x^2/4)-(x/2)=3/4 equation: 


x in (-oo:+oo)

(x^2)/4-(x/2) = 3/4 // - 3/4

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

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

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

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

DELTA = 1

DELTA > 0

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

x = 3 or x = -1

x in { -1, 3 }
