Solution for 0.25x^2-1/2x=1 equation: 


x in (-oo:+oo)

0.25*x^2-((1/2)*x) = 1 // - 1

0.25*x^2-((1/2)*x)-1 = 0

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

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

DELTA = (-1/2)^2-(-1*0.25*4)

DELTA = 5/4

DELTA > 0

x = ((5/4)^(1/2)+1/2)/(0.25*2) or x = (1/2-(5/4)^(1/2))/(0.25*2)

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

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