[ 1/1Inequality]
    Assignment:Find the solution set of inequality (4(k-1)^2)^2-4×(k^2+1)×(4×(k-1)×(k-3)) ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 4 * ( k - 1 ) ^ 2 ) ^ 2 - 4 × ( k ^ 2 + 1 ) × ( 4 × ( k - 1 ) × ( k - 3 ) ) ≥0         (1)

---

    From inequality(1)：
         k ≤ -1 或  k ≥ 1

---

    The final solution set is :
         k ≤ -1 或  k ≥ 1
