    Assignment:Find the solution set of inequality 3n＾2-13n-1900 ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * n ^ 2 - 13 * n - 1900 ≥0         (1)

---

    From inequality(1)：
         n ≤ -23.092545 或  n ≥ 27.425878

---

    The final solution set is :
         n ≤ -23.092545 或  n ≥ 27.425878
