[ 1/1Inequality]
    Assignment:Find the solution set of inequality (（√2）m+1)(（√2）m-1)（2m+1） <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( √ 2 ) * m + 1 ) * ( ( √ 2 ) * m - 1 ) * ( 2 * m + 1 ) <0         (1)

---

    From inequality(1)：
         m < -1/√2 或  -1/2 < m < 1/√2

---

    The final solution set is :
         m < -1/√2 或  -1/2 < m < 1/√2
