I could be totally off, but I just wanted to give it a shot. I got 8/3, 3 again, I could be way wrong, but I just wanted to try it/see if I remembered. good luck you know the formula right?

oh, I see how you got the 40. isn't it -4(a)(c) though? I got -24 + 16 to get -8 under the radical

$x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }=\frac{ 4 \pm \sqrt{16-4*3*(-2)} }{ 2*3 }= \frac{ 4 \pm \sqrt{40} }{ 6 }$ @rebecca1233
