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

---

    From inequality(1)：
         0 < x < 0.314596

---

    The final solution set is :
         0 < x < 0.314596
