You got D, right? now test it!! $$\dfrac{-3\pm i\sqrt {11}}{2}$$, right?

2. anonymous

yeah, how do i tag you?

3. Loser66

just pick + , that is $$\dfrac{-3 +i\sqrt{11}}{2}$$, replace to the original equation. that is $$14(\dfrac{-3 +i\sqrt{11}}{2})^2+42(\dfrac{-3 +i\sqrt{11}}{2})+70 =??$$

when you tag me, only me can see where your post is. So that I can click on the tagging box on top to know where you are. Let me go to other post and tag you. you can see the number appears on top. click it to see where I am.
