    Assignment:Find the solution set of inequality xx+21500x/57+200 <= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x * x + 21500 * x / 57 + 200 <= 0         (1)

---

    From inequality(1)：
         x ≤ -0.53098

---

    The final solution set is :
         x ≤ -0.53098
