Solution for h^2-5/2h-5,4=0 equation: 


h in (-oo:+oo)

h^2-((5/2)*h)-5.4 = 0

h^2+(-5/2)*h-5.4 = 0

h^2-5/2*h-5.4 = 0

DELTA = (-5/2)^2-(-5.4*1*4)

DELTA = 27.85

DELTA > 0

h = (27.85^(1/2)+5/2)/(1*2) or h = (5/2-27.85^(1/2))/(1*2)

h = (27.85^(1/2)+5/2)/2 or h = (5/2-27.85^(1/2))/2

h in { (5/2-27.85^(1/2))/2, (27.85^(1/2)+5/2)/2 }
