Question

Solve (x + 9)2 = 25

1. Apply the square root property of equality
2 Isolate the variable
Itx+95, then
If x +92 +5, then

Answer 1

x = - 14, x = - 4

Explanation:

Given

(x + 9)² = 25 ( take the square root of both sides )

x + 9 = ±
`√(25)` = ± 5

Subtract 9 from both sides

x = - 9 ± 5, that is

x = - 9 - 5 = - 14 or x = - 9 + 5 = - 4
