$x =(-2+ sqrt( - 36))/ (2)$
$x =(-2- sqrt( - 36))/ (2)$

Explanation:

Since ------- $2^2$ - $(4 xx1 xx 10)$ < 0, x has imaginary roots

$x =(-b+- sqrt(b^2 - (4ac)))/ (2a)$
$x =(-2+- sqrt(2^2 - (4xx1xx10)))/ (2xx1)$
$x =(-2+- sqrt(4 - 40))/ (2)$
$x =(-2+ sqrt( - 36))/ (2)$
$x =(-2- sqrt( - 36))/ (2)$
