((1-(3*x))^2)/3 = 25 // - 25
((1-(3*x))^2)/3-25 = 0
((1-3*x)^2)/3-25 = 0
((1-3*x)^2)/3+(-25*3)/3 = 0
(1-3*x)^2-25*3 = 0
9*x^2-6*x-74 = 0
9*x^2-6*x-74 = 0
9*x^2-6*x-74 = 0
DELTA = (-6)^2-(-74*4*9)
DELTA = 2700
DELTA > 0
x = (2700^(1/2)+6)/(2*9) or x = (6-2700^(1/2))/(2*9)
x = (30*3^(1/2)+6)/18 or x = (6-30*3^(1/2))/18
