x in (-oo:+oo)
3*x^2-((10/3)*x^2)-(13*x)-(4*x)-4 = 0
3*x^2+(-10/3)*x^2-13*x-4*x-4 = 0
-1/3*x^2-17*x-4 = 0
DELTA = (-17)^2-(-4*(-1/3)*4)
DELTA = 851/3
DELTA > 0
x = ((851/3)^(1/2)+17)/(-1/3*2) or x = (17-(851/3)^(1/2))/(-1/3*2)
x = -3/2*((851/3)^(1/2)+17) or x = -3/2*(17-(851/3)^(1/2))
x in { -3/2*((851/3)^(1/2)+17), -3/2*(17-(851/3)^(1/2)) }
