*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x^2\ +\ 2\ =\ 0]


Use the quadratic formula where *[tex \Large a\ =\ 1], *[tex \Large b\ =\ 0], and *[tex \Large c\ =\ 2]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = \frac{-b \pm sqrt{b^2 - 4ac}}{2a} ]



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = \frac{-(0) \pm sqrt{(0)^2 - 4(1)(2)}}{2(1)}\ =\ \frac{\pm\sqrt{-8}}{2}\ =\ \frac{\pm2i\sqrt{2}}{2}] 


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x = \pm i\sqrt{2} ]
