x in (-oo:+oo)
3*(x-(10/6))^2-(49/3) = -49/3 // + -49/3
3*(x-(10/6))^2-(49/3)-(-49/3) = 0
3*(x-5/3)^2-49/3+49/3 = 0
(3^2*(x-5/3)^2)/3-49/3+49/3 = 0
3^2*(x-5/3)^2-49+49 = 0
9*x^2-30*x-24+49 = 0
9*x^2-30*x+25 = 0
9*x^2-30*x+25 = 0
9*x^2-30*x+25 = 0
DELTA = (-30)^2-(4*9*25)
DELTA = 0
x = 30/(2*9)
x = 5/3 or x = 5/3
(x-5/3)^2 = 0
((x-5/3)^2)/3 = 0
((x-5/3)^2)/3 = 0 // * 3
(x-5/3)^2 = 0
x-5/3 = 0 // + 5/3
x = 5/3
