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


x in (-oo:+oo)

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

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

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

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

DELTA = 7/4

DELTA > 0

x = ((7/4)^(1/2)+1/2)/(3/4*2) or x = (1/2-(7/4)^(1/2))/(3/4*2)

x = 2/3*((7/4)^(1/2)+1/2) or x = 2/3*(1/2-(7/4)^(1/2))

x in { 2/3*(1/2-(7/4)^(1/2)), 2/3*((7/4)^(1/2)+1/2) }
