Split into two equations: (n + 3)^2 = 0 or (n + 5)^2 = 0
Take the square root of both sides: n + 3 = 0 or (n + 5)^2 = 0
Subtract 3 from both sides: n = -3 or (n + 5)^2 = 0
Take the square root of both sides: n = -3 or n + 5 = 0 Subtract 5 from both sides: Answer: n = -3 or n = -5 thus the Answer is wrong, neither -3 or -5 are a multiple of 4
