    Assignment:Find the solution set of inequality x^5+3*x^4-2*x^3+5*x^2-3*x-1 <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x ^ 5 + 3 * x ^ 4 - 2 * x ^ 3 + 5 * x ^ 2 - 3 * x - 1 <0         (1)

---

    From inequality(1)：
         x < -3.890868 或  -0.232326 < x < 0.761918

---

    The final solution set is :
         x < -3.890868 或  -0.232326 < x < 0.761918
