x in (-oo:+oo)
6*x^2+34*x+(40/3)*x+5 = 0
6*x^2+142/3*x+5 = 0
DELTA = (142/3)^2-(4*5*6)
DELTA = 19084/9
DELTA > 0
x = ((19084/9)^(1/2)-142/3)/(2*6) or x = (-(19084/9)^(1/2)-142/3)/(2*6)
x = ((19084/9)^(1/2)-142/3)/12 or x = (-((19084/9)^(1/2)+142/3))/12
x in { (-((19084/9)^(1/2)+142/3))/12, ((19084/9)^(1/2)-142/3)/12 }
