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

Answer:

Option B is correct

$x-3 = \pm \sqrt{7}$

Step-by-step explanation:

Given the equation:

$(x-3)^2 = 7$

taking square root both sides we have;

$\sqrt{(x-3)^2} = \pm \sqrt{7}$

Using exponent rules:

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

then;

$x-3 = \pm \sqrt{7}$

Therefore, the following statements follows from $(x-3)^2 = 7$ is, $x-3 = \pm \sqrt{7}$
