(x-(3/5))^2 = 4/5 // - 4/5
(x-(3/5))^2-(4/5) = 0
(x-3/5)^2-4/5 = 0
(5*(x-3/5)^2)/5-4/5 = 0
5*(x-3/5)^2-4 = 0
5*x^2-6*x-11/5 = 0
5*x^2-6*x-11/5 = 0
5*x^2-6*x-11/5 = 0
DELTA = (-6)^2-(-11/5*4*5)
DELTA = 80
DELTA > 0
x = (80^(1/2)+6)/(2*5) or x = (6-80^(1/2))/(2*5)
x = (4*5^(1/2)+6)/10 or x = (6-4*5^(1/2))/10
