Best ResponseYou've already chosen the best response.0see D = 180 so \[x = \frac{ 6 \pm \sqrt{180} }{ 2 }\]

Best ResponseYou've already chosen the best response.2hint: \[\Large \sqrt{20} = \sqrt{4*5}\] \[\Large \sqrt{20} = \sqrt{4}*\sqrt{5}\] \[\Large \sqrt{20} = 2*\sqrt{5}\]

Best ResponseYou've already chosen the best response.2You got to \[\Large x = \frac{6 \pm 3i\sqrt{20}}{2}\]

Best ResponseYou've already chosen the best response.2the root 20 can be replaced \[\Large x = \frac{6 \pm 3i*\sqrt{20}}{2}\] \[\Large x = \frac{6 \pm 3i*{\color{red}{\sqrt{20}}}}{2}\] \[\Large x = \frac{6 \pm 3i*{\color{red}{2\sqrt{5}}}}{2}\]

Best ResponseYou've already chosen the best response.2then you can factor out 2 from the numerator and cancel the '2's

Best ResponseYou've already chosen the best response.1Then that would leave me with 6+ 3i square root 5

Best ResponseYou've already chosen the best response.2you factor out 2 from the 6 as well \[\Large x = \frac{6 \pm 3i*2\sqrt{5}}{2}\] \[\Large x = \frac{2(3 \pm 3i\sqrt{5})}{2}\]

Best ResponseYou've already chosen the best response.2I think you meant to say `3+ 3i square root 5` if so then you are correct since the answers are \[\Large x = 3\pm3i\sqrt{5}\]
