Question

Solve by taking the square root of both sides: (x+3)^2 - 169 = 0

Answer 1

x = 10 x = -16

Explanation:

(x+3)^2 - 169 = 0

Add 169 to each side

(x+3)^2 - 169+169 = 0+169

(x+3)^2 =169

Take the square root of each side

sqrt((x+3)^2) =sqrt(169)

x+3 =±13

x+3 = 13 x+3 = -13

Subtract 3 from each side

x+3-3 = 13-3 x+3-3 = -13

x = 10 x = -16
