           ☆2 inequalities

[ 1/2Inequality]
    Assignment:Find the solution set of inequality a^2-6a-3 >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         a ^ 2 - 6 * a - 3 >= 0         (1)

---

    From inequality(1)：
         a ≤ -0.464102 或  a ≥ 6.464102

---

    The final solution set is :
         a ≤ -0.464102 或  a ≥ 6.464102
[ 2/2Inequality]
    Assignment:Find the solution set of inequality -1     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -1 < a         (1)
         a < -1 / 2         (2)

---

    From inequality(1)：
         a ＞ -1
    From inequality(2)：
         a < -1/2

---

    From inequalities (1) and (2)
         -1 < a < -1/2     (3)

---

    The final solution set is :
         -1 < a < -1/2
