    Assignment:Find the solution set of inequality (-2k-1)^2-4*4*(k-0.2) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( -2 * k - 1 ) ^ 2 - 4 * 4 * ( k - 0.2 ) >0         (1)

---

    From inequality(1)：
         k < 0.404555 或  k ＞ 2.595445

---

    The final solution set is :
         k < 0.404555 或  k ＞ 2.595445
