[ 1/1Inequality]
    Assignment:Find the solution set of inequality （4x^2+x^3+5x-6）÷（x^2-10x+21） ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 4 * x ^ 2 + x ^ 3 + 5 * x - 6 ) ÷ ( x ^ 2 - 10 * x + 21 ) ≥0         (1)

---

    From inequality(1)：
         0.716189 ≤ x ≤ 3 或  x ≥ 7

---

    The final solution set is :
         0.716189 ≤ x ≤ 3 或  x ≥ 7
