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


x in (-oo:+oo)

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

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

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

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

DELTA = 64/5

DELTA > 0

x = ((64/5)^(1/2)+4)/(4/5*2) or x = (4-(64/5)^(1/2))/(4/5*2)

x = 5/8*((64/5)^(1/2)+4) or x = 5/8*(4-(64/5)^(1/2))

x in { 5/8*(4-(64/5)^(1/2)), 5/8*((64/5)^(1/2)+4) }
