    Assignment:Find the solution set of inequality -10x²-1000x-2100 ≥3910 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -10 * x ^ 2 - 1000 * x - 2100 ≥3910         (1)

---

    From inequality(1)：
         -93.577517 ≤ x ≤ -6.422483

---

    The final solution set is :
         -93.577517 ≤ x ≤ -6.422483
