    Assignment:Find the solution set of inequality 586.350456-298.0028*n+33.86*n*n*n/6-1.2*9.94*n*n*n/6 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        586.350456 - 298.0028 * n + 33.86 * n * n * n / 6 - 1.2 * 9.94 * n * n * n / 6 >0         (1)

---

    From inequality(1)：
         -9.88686 < n < 2.077601 或  n ＞ 7.809259

---

    The final solution set is :
         -9.88686 < n < 2.077601 或  n ＞ 7.809259
