Question 5 • Algebra III A

Solve (x – 3)2 = 49. Select the values of x.

Answer
A
–46
B
-4
C
10
D
52

Explanation

Take the square root of both sides, remembering that a number whose square is 49 can be either 7 or −7. So x − 3 = 7 gives x = 10, and x − 3 = −7 gives x = −4. The correct choices are −4 and 10.
