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

---

    From inequality(1)：
         k ＞ 3/4

---

    The final solution set is :
         k ＞ 3/4
