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

    From inequality(1):
         -2 < a < 0 或  0 < a < 2
    From inequality(2):
         a < -2 或  a > -2

    From inequalities (1) and (2)
         -2 < a < 0 或  0 < a < 2     (3)

    The final solution set is :

         -2 < a < 0 或  0 < a < 2
