[ 1/1Inequality]
    Assignment:Find the solution set of inequality x＾3＋9x＾2＋x ≤102 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x ^ 3 + 9 * x ^ 2 + x ≤102         (1)

---

    From inequality(1)：
         x ≤ -6 或  -5.887482 ≤ x ≤ 2.887482

---

    The final solution set is :
         x ≤ -6 或  -5.887482 ≤ x ≤ 2.887482
