3x² – 5x – 2 = 0  ——> a = 3  ; b = – 5   ; c = – 2
x_{1} - x_{2} = frac{ sqrt{D} }{a}
         =  frac{ sqrt{ b^{2}- 4.a.c } }{a}
         =  frac{ sqrt{ (-5)^{2}- 4 . 3 ..(-2) } }{3}
         =  frac{ sqrt{25 + 24}}{3}
         =  frac{ sqrt{49}}{3}
         =  frac{7}{3}

3x^2-5x-2 = 0        x1>x2
faktorin
jadi (x-2)(3x+1)
x1=2
x2=-1/3

x1-x2 = 2+1/3 = 6+1/3 = 7/3
