Use the quadratic formula to solve the equation. Be sure to simplify your answers. Enter both answers separated by a comma.

x2−2x−6=0\displaystyle {x}^{{2}}-{2}{x}-{6}={0}


For example, if x=−5±154\displaystyle {x}=\frac{{-{5}\pm\sqrt{{{15}}}}}{{4}} you enter

(-5-sqrt(15))/4 on the left and (-5+sqrt(15))/4 on the right.
