Answer:
[tex]x-3=\pm\sqrt{7}[/tex]
Step-by-step explanation:
We have been given an equation [tex](x-3)^2=7[/tex]. We are asked to choose the correct answer about our given equation.
To solve our given equation, we will take square root of both sides of our equation as:
[tex]\sqrt{(x-3)^2}=\pm\sqrt{7}[/tex]
Using radical rule [tex]\sqrt[n]{a^n}=a[/tex], we will get:
[tex]x-3=\pm\sqrt{7}[/tex]
Therefore, option B is the correct choice.
