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

---

    From inequality(1)：
         0.267949 < x < 1 或  1 < x < 3.732051

---

    The final solution set is :
         0.267949 < x < 1 或  1 < x < 3.732051
