    Assignment:Find the solution set of inequality -13.453×n×n-0.9684×n×n×n+7984.74276-120.994×n ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -13.453 × n × n - 0.9684 × n × n × n + 7984.74276 - 120.994 × n ≥0         (1)

---

    From inequality(1)：
         n ≤ 14.892982

---

    The final solution set is :
         n ≤ 14.892982
