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

---

    From inequality(1)：
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!

---

    The final solution set is :
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!
