Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2} +10x+16=0$

$a=1\\b=10\\c=16$

substitute in the formula

$x=\frac{-10(+/-)\sqrt{10^{2}-4(1)(16)}} {2(1)}$

$x=\frac{-10(+/-)\sqrt{36}}{2}$

$x=\frac{-10(+/-)6}{2}$

$x=\frac{-10(+)6}{2}=-2$

$x=\frac{-10(-)6}{2}=-8$
