[ 1/1Inequality]
    Assignment:Find the solution set of inequality （-a/2）^2+a*(-a/2)+3 >= a .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( -a / 2 ) ^ 2 + a * ( -a / 2 ) + 3 >= a         (1)

---

    From inequality(1)：
         -6 ≤ a ≤ 2

---

    The final solution set is :
         -6 ≤ a ≤ 2
