Best ResponseYou've already chosen the best response.1\(3x^24x+3=0\implies \dfrac{(4)\pm \sqrt{(4)^24(3)(3)}}{2(3)}=\dfrac{4\pm\sqrt{1636}}{6}\\=\dfrac{4\pm2\sqrt{5}i}{6}=\dfrac{2\pm\sqrt{5}i}{3}\)

Best ResponseYou've already chosen the best response.1\(\dfrac{4\pm2\sqrt{5}i}{6}=\dfrac{2(2+\sqrt{5}i)}{2*3}=(\dfrac{2}{2})\dfrac{2+\sqrt{5}i}{3}=(\dfrac{\cancel{2}}{\cancel{2}})\dfrac{2+\sqrt{5}i}{3}=\dfrac{2\pm\sqrt{5}i}{3}=\dfrac{2\pm i\sqrt{5}}{3}\)

Best ResponseYou've already chosen the best response.1\(\dfrac{4\pm2\sqrt{5}i}{6}=\dfrac{2(2+\sqrt{5}i)}{2*3}=(\dfrac{2}{2})\dfrac{2+\sqrt{5}i}{3}=(\dfrac{\cancel{2}}{\cancel{2}})\dfrac{2+\sqrt{5}i}{3}=\\\dfrac{2\pm\sqrt{5}i}{3}=\dfrac{2\pm i\sqrt{5}}{3}\)
