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

    From inequality(1):
         x ≤ -2 或  x ≥ 2
    From inequality(2):
         x ∈ R (R为全体实数),即在实数范围内,不等式恒成立!

    From inequalities (1) and (2)
         x ≤ -2 或  x ≥ 2    (3)

    The final solution set is :

         x ≤ -2 或  x ≥ 2
