Solution for z^2-3z/2-6=0 equation: 


z in (-oo:+oo)

z^2-((3*z)/2)-6 = 0

z^2+(-3/2)*z-6 = 0

z^2-3/2*z-6 = 0

DELTA = (-3/2)^2-(-6*1*4)

DELTA = 105/4

DELTA > 0

z = ((105/4)^(1/2)+3/2)/(1*2) or z = (3/2-(105/4)^(1/2))/(1*2)

z = ((105/4)^(1/2)+3/2)/2 or z = (3/2-(105/4)^(1/2))/2

z in { (3/2-(105/4)^(1/2))/2, ((105/4)^(1/2)+3/2)/2 }
