[ 1/2Inequality]
    Assignment:Find the solution set of inequality (m+2)^2-2m(m+2)+4 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( m + 2 ) ^ 2 - 2 * m * ( m + 2 ) + 4 >0         (1)

---

    From inequality(1)：
         -√8 < m < √8

---

    The final solution set is :
         -√8 < m < √8
[ 2/2Inequality]
    Assignment:Find the solution set of inequality (m-1)^2-2m(m-1)+4 <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( m - 1 ) ^ 2 - 2 * m * ( m - 1 ) + 4 <0         (1)

---

    From inequality(1)：
         m < -√5 或  m ＞ √5

---

    The final solution set is :
         m < -√5 或  m ＞ √5
