    Assignment:Find the solution set of inequality 12k-(k^2+k-6) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        12 * k - ( k ^ 2 + k - 6 ) <0         (1)

---

    From inequality(1)：
         k < -0.520797 或  k ＞ 11.520797

---

    The final solution set is :
         k < -0.520797 或  k ＞ 11.520797
