B Correct answer
Explanation

(x-3)^2 = 4 implies x-3 = 2 or x-3 = -2. Thus x = 5 or x = 1.

AI explanation

To solve (x - 3)2 = 4, take the square root of both sides to get x - 3 equal to 2 or -2. Adding 3 to both sides of each equation gives x equal to 5 or x equal to 1. Therefore, the roots of the equation are +5 and +1.
