$x^2 + 2x - 6 = 2$ $\implies$ $x^2 + 2x - 8$

By Vieta's Formula ,

The sum of the roots is

$x_1 + x_2 = \frac{-B}{A} = \frac{-2}{1} = -2$

The product of the roots is

$x_1x_2 = \frac{C}{A} = \frac{-8}{1} = -8$

Adding the sum and the product of the roots, we get

$(x_1 + x_2) + x_1x_2 = -2 + (-8) =$ $\boxed{-10}$
