    Assignment:Find the solution set of inequality （X-2）x（X-2） ≥1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( X - 2 ) * X * ( X - 2 ) ≥1         (1)

---

    From inequality(1)：
         0.381966 ≤ X ≤ 1 或  X ≥ 2.618034

---

    The final solution set is :
         0.381966 ≤ X ≤ 1 或  X ≥ 2.618034
