    Assignment:Find the solution set of inequality 4x^2-100x-1200 >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        4 * x ^ 2 - 100 * x - 1200 >= 0         (1)

---

    From inequality(1)：
         x ≤ -8.860009 或  x ≥ 33.860009

---

    The final solution set is :
         x ≤ -8.860009 或  x ≥ 33.860009
