Solution for (1/2x^2)-(3/2x)-(7/4)=0 equation: 


x in (-oo:+oo)

(1/2)*x^2-((3/2)*x)-(7/4) = 0

(1/2)*x^2+(-3/2)*x-7/4 = 0

1/2*x^2-3/2*x-7/4 = 0

DELTA = (-3/2)^2-(-7/4*1/2*4)

DELTA = 23/4

DELTA > 0

x = ((23/4)^(1/2)+3/2)/(1/2*2) or x = (3/2-(23/4)^(1/2))/(1/2*2)

x = (23/4)^(1/2)+3/2 or x = 3/2-(23/4)^(1/2)

x in { 3/2-(23/4)^(1/2), (23/4)^(1/2)+3/2 }
