[ 1/1Inequality]
    Assignment:Find the solution set of inequality X-1 <2/X     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         X - 1 <2 / X         (1)
        2 / X < X / 2         (2)
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         X < -1 或  0 < X < 2
    From inequality(2)：
         -2 < X < 0 或  X ＞ 2
    From inequality(3)：
         X < 0 或  X ＞ 0

---

    From inequalities (1) and (2)
         -2 < X < -1 或     (4)
    From inequalities (3) and (4)
         -2 < X < -1     (5)

---

    The final solution set is :
         -2 < X < -1
