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

    From inequality(1):
         x < -1
    From inequality(2):
         x < 0 或  x > 0
    From inequality(3):
         x < -1 或  x > -1
    From inequality(4):
         x < 0 或  x > 0

    From inequalities (1) and (2)
         x < -1    (5)
    From inequalities (3) and (5)
         x < -1    (6)
    From inequalities (4) and (6)
         x < -1    (7)

    The final solution set is :

         x < -1
