[ 1/1Inequality]
    Assignment:Find the solution set of inequality (x-1)^4x^2(x+1)^6÷(x-3)^3(x+4)^5 ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x - 1 ) ^ 4 * x ^ 2 * ( x + 1 ) ^ 6 ÷ ( x - 3 ) ^ 3 * ( x + 4 ) ^ 5 ≤0         (1)

---

    From inequality(1)：
         -4 ≤ x ≤ -1 或  -1 ≤ x ≤ -1 或  -1 ≤ x ≤ 0 或  0 ≤ x ≤ 0 或  0 ≤ x ≤ 1 或  1 ≤ x ≤ 1 或  1 ≤ x ≤ 2.9999

---

    The final solution set is :
         -4 ≤ x ≤ -1 或  -1 ≤ x ≤ -1 或  -1 ≤ x ≤ 0 或  0 ≤ x ≤ 0 或  0 ≤ x ≤ 1 或  1 ≤ x ≤ 1 或  1 ≤ x ≤ 2.9999
