((x-2)^2)/3 = ((13*x-66)^1)/3 // - ((13*x-66)^1)/3
((x-2)^2)/3-(((13*x-66)^1)/3) = 0
((x-2)^2)/3-((13*x-66)/3) = 0
((x-2)^2)/3+(-1*(13*x-66))/3 = 0
(x-2)^2-1*(13*x-66) = 0
x^2-17*x+70 = 0
x^2-17*x+70 = 0
x^2-17*x+70 = 0
DELTA = (-17)^2-(1*4*70)
DELTA = 9
DELTA > 0
x = (9^(1/2)+17)/(1*2) or x = (17-9^(1/2))/(1*2)
x = 10 or x = 7
(x-7)*(x-10) = 0
((x-7)*(x-10))/3 = 0
((x-7)*(x-10))/3 = 0 // * 3
(x-7)*(x-10) = 0
( x-10 )
x-10 = 0 // + 10
x = 10
( x-7 )
x-7 = 0 // + 7
x = 7
