Solution for 1.4*10^-11=x^2/0.25-x equation: 


x in (-oo:+oo)

1.4*10^-11 = (x^2)/0.25-x // - (x^2)/0.25-x

x-((x^2)/0.25)+1.4*10^-11 = 0

x-4*x^2+1.4*10^-11 = 0

x-4*x^2 = 0

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

DELTA = 1

DELTA > 0

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

x = 0 or x = 1/4

x in { 0, 1/4 }
