[ 1/1Inequality]
    Assignment:Find the solution set of inequality 2x＾3＋18x＾2＋x ≤1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2 * x ^ 3 + 18 * x ^ 2 + x ≤1         (1)

---

    From inequality(1)：
         x ≤ -8.937799 或  -0.269658 ≤ x ≤ 0.207456

---

    The final solution set is :
         x ≤ -8.937799 或  -0.269658 ≤ x ≤ 0.207456
