Solution for x^2/0.64-x=0.47 equation: 


x in (-oo:+oo)

(x^2)/0.64-x = 0.47 // - 0.47

(x^2)/0.64-x-0.47 = 0

1.5625*x^2-x-0.47 = 0

DELTA = (-1)^2-(-0.47*1.5625*4)

DELTA = 3.9375

DELTA > 0

x = (3.9375^(1/2)+1)/(1.5625*2) or x = (1-3.9375^(1/2))/(1.5625*2)

x = 0.32*(3.9375^(1/2)+1) or x = 0.32*(1-3.9375^(1/2))

x in { 0.32*(1-3.9375^(1/2)), 0.32*(3.9375^(1/2)+1) }
