    Assignment:Find the solution set of inequality （2k-1）²-4×1×k²+1 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * k - 1 ) ^ 2 - 4 × 1 × k ^ 2 + 1 >0         (1)

---

    From inequality(1)：
         k < 1/2

---

    The final solution set is :
         k < 1/2
