![\Large \boxed{\mathrm{Option \ 2}}](https://tex.z-dn.net/?f=%5CLarge%20%5Cboxed%7B%5Cmathrm%7BOption%20%5C%202%7D%7D)
Step-by-step explanation:
![2x^2 =16](https://tex.z-dn.net/?f=2x%5E2%20%3D16)
The square root property requires a quantity squared by itself on one side of the equation. The only quantity squared is x, so divide both sides by 2 before applying the square root property.
The x variable should be isolated on one side of the equation. The x variable is squared so before performing the square root property where we take the square root of both sides, we divide both sides by 2, then take the square root of both sides.
Dividing both sides by 2.
![\displaystyle \frac{2x^2 }{2} =\frac{16}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B2x%5E2%20%7D%7B2%7D%20%3D%5Cfrac%7B16%7D%7B2%7D)
![x^2 =8](https://tex.z-dn.net/?f=x%5E2%20%3D8)
Taking the square root of both sides.
![\sqrt{x^2 } =\pm \sqrt{8}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2%20%7D%20%3D%5Cpm%20%5Csqrt%7B8%7D)
![x=\pm 2\sqrt{2}](https://tex.z-dn.net/?f=x%3D%5Cpm%202%5Csqrt%7B2%7D)

75,314 because it is only 5 numbers so this is correct.
Answer:
x² - 16xy + 64y²
Step-by-step explanation:
The difference of x and 8y is x - 8y
The square of the difference is (x - 8y)² = (x - 8y)(x - 8y)
Expand by multiplying each term in the second factor by each term in the first factor, that is
x(x - 8y) - 8y(x - 8y) ← distribute both parenthesis
= x² - 8xy - 8xy + 64y² ← collect like terms
= x² - 16xy + 64y²
