Solve x^2+2x+7=0 using the quadratic formula.
Aneli [31]

Answer:

x=-1\pm \sqrt{6}i

Step-by-step explanation:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\frac{-(2)\pm\sqrt{2^2-4(1)(7)}}{2(1)}

x=\frac{-2\pm\sqrt{4-28}}{2}

x=\frac{-2\pm\sqrt{-24}}{2}

x=\frac{-2\pm\sqrt{-1*24}}{2}

x=\frac{-2\pm\sqrt{-1}\sqrt{24}}{2}

x=\frac{-2\pm i\sqrt{4*6}}{2}

x=\frac{-2\pm i\sqrt{4}\sqrt{6}}{2}

x=\frac{-2\pm2i\sqrt{6}}{2}

x=-1\pm \sqrt{6}i
