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

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

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