[ 1/1Inequality]
    Assignment:Find the solution set of inequality (3+4i)/(2+i) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 3 + 4 * i ) / ( 2 + i ) >0         (1)
        From the definition field of divisor
         2 + x ≠ 0        (2 )

---

    From inequality(1)：
         i < -2 或  i ＞ -3/4
    From inequality(2)：
         i < -2 或  i ＞ -2

---

    From inequalities (1) and (2)
         i < -2 或  i ＞ -3/4    (3)

---

    The final solution set is :
         i < -2 或  i ＞ -3/4
