    Assignment:Find the solution set of inequality x^4+8x^3+9x^2-7x-10 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x ^ 4 + 8 * x ^ 3 + 9 * x ^ 2 - 7 * x - 10 >0         (1)

---

    From inequality(1)：
         x < -6.481541 或  x ＞ 0.973671

---

    The final solution set is :
         x < -6.481541 或  x ＞ 0.973671
