Best ResponseYou've already chosen the best response.0if you haven't learned about imaginary number (I am talking about "i") then simply say no solution. Now, if you have lets go on... \[\huge\color{goldenrod}{ \frac{8±4i \sqrt{3}}{8} }\] and divide top and bottom by 4, \[\huge\color{cornflowerblue}{ \frac{2±i \sqrt{3}}{2} }\]
