    Assignment:Find the solution set of inequality 6xxxxx-25xxxx+72xx-16x-49 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        6 * x * x * x * x * x - 25 * x * x * x * x + 72 * x * x - 16 * x - 49 >0         (1)

---

    From inequality(1)：
         -1.29803 < x < -0.835447 或  1.231858 < x < 1.978705 或  x ＞ 3.089581

---

    The final solution set is :
         -1.29803 < x < -0.835447 或  1.231858 < x < 1.978705 或  x ＞ 3.089581
