Question

Find the solution(s) to (x+ 3)2 = 49. Check all that apply.

. A. x= -10
] B. X =-7
C. x =4
. D. x =7
0 E.X=-4

Answer 1

A) x - = -10

C) x = 4

Explanation:

(x + 3)² = 49

(x + 3)² = 7²

Take square root both sides,

`\sf √((x + 3)^2)=√(7^2)`

x + 3 = ± 7

x + 3 = +7 ; x + 3 = -7

x = 7 - 3 ; x = -7 -3

x = 4 ; x = -10

x = 4 , -10
