Answer:

(x + 1)(x + 9) = 0

Step-by-step explanation:

After you subtract 16 from both sides, you get ...

x² +10x +9 = 0

When you factor this equation, it becomes ...

(x +1)(x +9) = 0

_____

For the zero product property to be of any use, the form of the equation must be a product that equals zero.

___

<em>Comment on the other answer choice</em>

(x -1)(x -9) = 0 = x² -10x +9 . . . . . the x term is different from that in the given equation. It has the wrong sign.
