[ 1/1Inequality]
    Assignment:Find the solution set of inequality (4k/(k+1))^2 >2.4 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 4 * k / ( k + 1 ) ) ^ 2 >2.4         (1)
        From the definition field of divisor
         x + 1 ≠ 0        (2 )

    From inequality(1):
         k < -0.279175 或  k > 0.632116
    From inequality(2):
         k < -1 或  k > -1

    From inequalities (1) and (2)
         k < -1 或  -1 < k < -0.279175 或  k > 0.632116    (3)

    The final solution set is :

         k < -1 或  -1 < k < -0.279175 或  k > 0.632116
