The proportion page states that the square root of 16 is 4 or -4.

The square root of 16 is 4.

-4 is the opposite of the square root of 16.

Good call. In a physical proportion problem, the Domain would be x > 0. Why would one EVER bring up -4? Let's talk about the Domain in the little parentheses, rather than the very odd "-4".
