Answer:

x = - 4

Explanation:

Given

(2x + 8)² = 0, then

2x + 8 = 0 ( subtract 8 from both sides )

2x = - 8 ( divide both sides by 2 )

x = - 4

(2x+8)²=0

Whenever a product is zero (and a square is a product) then there are solutions when either factor is zero. Here they're both the same, so

2x + 8 = 0

2x = -8

x = -4

Answer: -4
