[ 1/2Inequality]
    Assignment:Find the solution set of inequality x^2+5x+4 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x ^ 2 + 5 * x + 4 >0         (1)

---

    From inequality(1)：
         x < -4 或  x ＞ -1

---

    The final solution set is :
         x < -4 或  x ＞ -1
[ 2/2Inequality]
    Assignment:Find the solution set of inequality x^2+5x-14 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x ^ 2 + 5 * x - 14 >0         (1)

---

    From inequality(1)：
         x < -7 或  x ＞ 2

---

    The final solution set is :
         x < -7 或  x ＞ 2
