Solution for 1/4x^2-5x-5=0 equation: 


x in (-oo:+oo)

(1/4)*x^2-(5*x)-5 = 0

(1/4)*x^2-5*x-5 = 0

1/4*x^2-5*x-5 = 0

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

DELTA = 30

DELTA > 0

x = (30^(1/2)+5)/(1/4*2) or x = (5-30^(1/2))/(1/4*2)

x = 2*(30^(1/2)+5) or x = 2*(5-30^(1/2))

x in { 2*(5-30^(1/2)), 2*(30^(1/2)+5) }
