Best ResponseYou've already chosen the best response.0\[\frac{6\pm\sqrt{3612}}{6}\] \[\frac{6\pm\sqrt{24}}{6}\] \[\frac{6\pm2\sqrt{6}}{6}\] \[\frac{2(3\pm\sqrt{6})}{6}\] \[\frac{3\pm\sqrt{6}}{3}\]

Best ResponseYou've already chosen the best response.0only gimmick is \[24=4\times 6\] so \[\sqrt{24}=\sqrt{4}\sqrt{6}=2\sqrt{6}\] and you can cancel with the denominator. make sure to factor before you cancel

Best ResponseYou've already chosen the best response.0last question: why is it 3 +/ √6 / 3 in the end? When before it it's 2 (3 +/ √6)/6?
