    Assignment:Find the solution set of inequality （k-1）^2-8(k+3) ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( k - 1 ) ^ 2 - 8 * ( k + 3 ) ≥0         (1)

---

    From inequality(1)：
         k ≤ -1.928203 或  k ≥ 11.928203

---

    The final solution set is :
         k ≤ -1.928203 或  k ≥ 11.928203
