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

---

    From inequality(1)：
         -1.656854 < a < 9.656854
    From inequality(2)：
         a < 0 或  a ＞ 0

---

    From inequalities (1) and (2)
         -1.656854 < a < 0 或  0 < a < 9.656854     (3)

---

    The final solution set is :
         -1.656854 < a < 0 或  0 < a < 9.656854
