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

---

    From inequality(1)：
         a < -1.081139 或  a ＞ 2.081139

---

    The final solution set is :
