Solution for -(2/25x^2-x-1/4) equation: 


x in (-oo:+oo)

-((2/25)*x^2-x-(1/4)) = 0

-((2/25)*x^2-x-1/4) = 0

x-2/25*x^2+1/4 = 0

DELTA = 1^2-(-2/25*1/4*4)

DELTA = 27/25

DELTA > 0

x = ((27/25)^(1/2)-1)/(-2/25*2) or x = (-(27/25)^(1/2)-1)/(-2/25*2)

x = -25/4*((27/25)^(1/2)-1) or x = 25/4*((27/25)^(1/2)+1)

x in { -25/4*((27/25)^(1/2)-1), 25/4*((27/25)^(1/2)+1) }
