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

---

    From inequality(1)：
         0 < x < 0.278465
    From inequality(2)：
         x ＞ 0
    From inequality(3)：
         x < -2 或  -2 < x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         0 < x < 0.278465     (4)
    From inequalities (3) and (4)
         0 < x < 0.278465     (5)

---

    The final solution set is :
         0 < x < 0.278465
