[ 1/1Inequality]
    Assignment:Find the solution set of inequality （k^2+4k+4）^2-4k*（16-k^2） <= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( k ^ 2 + 4 * k + 4 ) ^ 2 - 4 * k * ( 16 - k ^ 2 ) <= 0         (1)

---

    From inequality(1)：
         -8.860919 ≤ k ≤ -4.160413

---

    The final solution set is :
         -8.860919 ≤ k ≤ -4.160413
