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

---

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

---

    From inequalities (1) and (2)
         x < -1    (3)

---

    The final solution set is :
         x < -1
