[ 1/1Inequality]
    Assignment:Find the solution set of inequality 120x^7-151x^6+31 ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        120 * x ^ 7 - 151 * x ^ 6 + 31 ≤0         (1)

---

    From inequality(1)：
         x ≤ -0.712712 或  1 ≤ x ≤ 1.141668

---

    The final solution set is :
         x ≤ -0.712712 或  1 ≤ x ≤ 1.141668
