    Assignment:Find the solution set of inequality 25 >6x²+2x >13 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        25 >6 * x ^ 2 + 2 * x         (1)
        6 * x ^ 2 + 2 * x >13         (2)

---

    From inequality(1)：
         -2.214701 < x < 1.881368
    From inequality(2)：
         x < -1.648032 或  x ＞ 1.314699

---

    From inequalities (1) and (2)
         -2.214701 < x < -1.648032 或  1.314699 < x < 1.881368     (3)

---

    The final solution set is :
         -2.214701 < x < -1.648032 或  1.314699 < x < 1.881368
