Solution for x^2+3x-5/2x-1 equation: 


x in (-oo:+oo)

x^2+3*x-((5/2)*x)-1 = 0

x^2+3*x+(-5/2)*x-1 = 0

x^2+1/2*x-1 = 0

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

DELTA = 17/4

DELTA > 0

x = ((17/4)^(1/2)-1/2)/(1*2) or x = (-(17/4)^(1/2)-1/2)/(1*2)

x = ((17/4)^(1/2)-1/2)/2 or x = (-((17/4)^(1/2)+1/2))/2

x in { (-((17/4)^(1/2)+1/2))/2, ((17/4)^(1/2)-1/2)/2 }
