[ 1/1Inequality]
    Assignment:Find the solution set of inequality 4     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        4 < x ^ 2         (1)
         x ^ 2 ≤9         (2)

---

    From inequality(1)：
         x < -2 或  x ＞ 2
    From inequality(2)：
         -3 ≤ x ≤ 3

---

    From inequalities (1) and (2)
         -3 ≤ x < -2 或  2 < x ≤ 3     (3)

---

    The final solution set is :
         -3 ≤ x < -2 或  2 < x ≤ 3
