[ 1/1Inequality]
    Assignment:Find the solution set of inequality (7-x)(3-x)(4-x*x) <= 100 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 7 - x ) * ( 3 - x ) * ( 4 - x * x ) <= 100         (1)

---

    From inequality(1)：
         x ≤ -350781/500000 或  -350781/500000 ≤ x ≤ -350781/500000 或  -350781/500000 ≤ x ≤ 2850781/500000 或  2850781/500000 ≤ x ≤ 2850781/500000 或  x ≥ 2850781/500000

---

    The final solution set is :
         x ≤ -350781/500000 或  -350781/500000 ≤ x ≤ -350781/500000 或  -350781/500000 ≤ x ≤ 2850781/500000 或  2850781/500000 ≤ x ≤ 2850781/500000 或  x ≥ 2850781/500000
