[ 1/1Inequality]
    Assignment:Find the solution set of inequality abs(b+1-sqrt(b^2-2b-3)-6*b*((b+1-sqrt(b^2-2b-3))/2b)^2+4*b*((b+1-sqrt(b^2-2b-3))/2b)^3)小于1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         abs ( b + 1 - sqrt ( b ^ 2 - 2 * b - 3 ) - 6 * b * ( ( b + 1 - sqrt ( b ^ 2 - 2 * b - 3 ) ) / 2 * b ) ^ 2 + 4 * b * ( ( b + 1 - sqrt ( b ^ 2 - 2 * b - 3 ) ) / 2 * b ) ^ 3 ) <1         (1)
        From the definition field of √
         x ^ 2 - 2 * x - 3 ≥ 0        (2 )
        From the definition field of √
         x ^ 2 - 2 * x - 3 ≥ 0        (3 )
        From the definition field of √
         x ^ 2 - 2 * x - 3 ≥ 0        (4 )

    From inequality(1):
         -1.473801 < b < -1.364263 或  b > -1.258419
    From inequality(2):
         b ≤ -1 或  b ≥ 3
    From inequality(3):
         b ≤ -1 或  b ≥ 3
    From inequality(4):
         b ≤ -1 或  b ≥ 3

    From inequalities (1) and (2)
         -1.473801 < b < -1.364263 或  -1.258419 < b ≤ -1 或  b ≥ 3    (5)
    From inequalities (3) and (5)
         -1.473801 < b < -1.364263 或  -1.258419 < b ≤ -1 或  b ≥ 3    (6)
    From inequalities (4) and (6)
         -1.473801 < b < -1.364263 或  -1.258419 < b ≤ -1 或  b ≥ 3    (7)

    The final solution set is :

         -1.473801 < b < -1.364263 或  -1.258419 < b ≤ -1 或  b ≥ 3
