Question

Which of the following statements follows from (x - 3)2 = 7?

x2 + 9 = 7

x - 3 = ±

x - 3 = ±49

Answer 1

the first one hope this clarifies

Answer 2

Option B is correct

`x-3 = \pm √(7)`

Explanation:

Given the equation:

`(x-3)^2 = 7`

taking square root both sides we have;

`√((x-3)^2) = \pm √(7)`

Using exponent rules:

`\sqrt[n]{x^n}=x`

then;

`x-3 = \pm √(7)`

Therefore, the following statements follows from
`(x-3)^2 = 7` is,
`x-3 = \pm √(7)`
