    Assignment:Find the solution set of inequality x^4-4*x^3+4*x^2-4*x+4 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x ^ 4 - 4 * x ^ 3 + 4 * x ^ 2 - 4 * x + 4 >0         (1)

---

    From inequality(1)：
         x < 1.22527 或  x ＞ 2.946965

---

    The final solution set is :
         x < 1.22527 或  x ＞ 2.946965
