[ 1/1Inequality]
    Assignment:Find the solution set of inequality 3     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        3 < x + sqrt ( x ^ 2 - 4 )         (1)
         x + sqrt ( x ^ 2 - 4 ) <4         (2)
        From the definition field of √
         x ^ 2 - 4 ≥ 0        (3 )

---

    From inequality(1)：
         x ＞ 13/6
    From inequality(2)：
         x < 5/2
    From inequality(3)：
         x ≤ -2 或  x ≥ 2

---

    From inequalities (1) and (2)
         13/6 < x < 5/2     (4)
    From inequalities (3) and (4)
         13/6 < x < 5/2     (5)

---

    The final solution set is :
         13/6 < x < 5/2
