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

---

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

---

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

---

    The final solution set is :
         -1/3 < x < 1
