[ 1/2Inequality]
    Assignment:Find the solution set of inequality -2m^3+6m >= -4 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -2 * m ^ 3 + 6 * m >= -4         (1)

---

    From inequality(1)：
         m ≤ -1 或  -1 ≤ m ≤ -1 或  -1 ≤ m ≤ 2

---

    The final solution set is :
         m ≤ -1 或  -1 ≤ m ≤ -1 或  -1 ≤ m ≤ 2
[ 2/2Inequality]
    Assignment:Find the solution set of inequality -2m^3+6m <= 4 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -2 * m ^ 3 + 6 * m <= 4         (1)

---

    From inequality(1)：
         -2 ≤ m ≤ 1 或  1 ≤ m ≤ 1 或  m ≥ 1

---

    The final solution set is :
         -2 ≤ m ≤ 1 或  1 ≤ m ≤ 1 或  m ≥ 1
