x in (-oo:+oo)
(x^2-(4*x))/6-((5*x)/3) = 1 // - 1
(x^2-(4*x))/6-((5*x)/3)-1 = 0
(x^2-4*x)/6+(-5/3)*x-1 = 0
(x^2-4*x)/6+(-5*x)/3-1 = 0
(3*(x^2-4*x))/(3*6)+(-5*6*x)/(3*6)+(-1*3*6)/(3*6) = 0
3*(x^2-4*x)-5*6*x-1*3*6 = 0
3*x^2-42*x-18 = 0
3*x^2-42*x-18 = 0
3*(x^2-14*x-6) = 0
x^2-14*x-6 = 0
DELTA = (-14)^2-(-6*1*4)
DELTA = 220
DELTA > 0
x = (220^(1/2)+14)/(1*2) or x = (14-220^(1/2))/(1*2)
x = (2*55^(1/2)+14)/2 or x = (14-2*55^(1/2))/2
