    Solve for n:
    (n + 3)^2 (n + 5)^2 = 0

    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
