Solution for 3/2x^2-5/2x-7 equation: 


x in (-oo:+oo)

(3/2)*x^2-((5/2)*x)-7 = 0

(3/2)*x^2+(-5/2)*x-7 = 0

3/2*x^2-5/2*x-7 = 0

DELTA = (-5/2)^2-(-7*3/2*4)

DELTA = 193/4

DELTA > 0

x = ((193/4)^(1/2)+5/2)/(3/2*2) or x = (5/2-(193/4)^(1/2))/(3/2*2)

x = ((193/4)^(1/2)+5/2)/3 or x = (5/2-(193/4)^(1/2))/3

x in { (5/2-(193/4)^(1/2))/3, ((193/4)^(1/2)+5/2)/3 }
