Answer:

The solutions are -8 and -2

Explanation:

The equation is this:

x^2 + 10x + 16

Next you get:

(x + 8)(x + 2)

You know this is correct if you multiply it.

(x * x) + (x * 2) + (8 * x) + (8 * 2) = x^2 + 10x + 16

Now to find the solutions otherwise known as the zeros of the equations.

(x + 8)(x + 2) = 0

The zeros cancel out the numbers within the parenthesis.

x + 8 = 0

x = -8

__

x + 2 = 0

x = -2

Hope this helps
