Solution for 1/4x^2-4x0 equation: 


x in (-oo:+oo)

(1/4)*x^2-(4*x) > 0

(1/4)*x^2-4*x > 0

1/4*x^2-4*x > 0

DELTA = (-4)^2-(0*1/4*4)

DELTA = 16

DELTA > 0

x = (16^(1/2)+4)/(1/4*2) or x = (4-16^(1/2))/(1/4*2)

x = 16 or x = 0

a = 1/4

a > 0

x in (-oo:0) U (16:+oo)

x in (-oo:0) U (16:+oo)

(-oo:0) U (16:+oo)
