$-6$

$(5x^2 - 2x + 5) + (-5x^2 + 2x - 11)$

$5x^2 - 2x + 5 - 5x^2 + 2x - 11$

Combine like terms:
$color(red)(cancel(5x^2)) quadcolor(blue)(cancel(-quad2x)) + 5 color(red)(cancel(- 5x^2)) quadcolor(blue)(cancel(+quad2x)) - 11$

All that is left is $5-11$ , which simplifies to $-6$ .

Hope this helps!
