Question 2 • AZ-Common Core Algebra II A

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

Answer
A
–46
B
-4
C
10
D
52

Explanation

Taking the 2 as an exponent, (x − 3)² = 49 means x − 3 = 7 or x − 3 = −7, since both 7² and (−7)² equal 49. Adding 3 gives x = 10 or x = −4, so the correct values are −4 and 10.
