[ 1/1Inequality]
    Assignment:Find the solution set of inequality 4x/(x-8)*(x+6) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        4 * x / ( x - 8 ) * ( x + 6 ) >0         (1)
        From the definition field of divisor
         x - 8 ≠ 0        (2 )

---

    From inequality(1)：
         -6 < x < 0 或  x ＞ 8
    From inequality(2)：
         x < 8 或  x ＞ 8

---

    From inequalities (1) and (2)
         -6 < x < 0 或  x ＞ 8    (3)

---

    The final solution set is :
         -6 < x < 0 或  x ＞ 8
