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

---

    From inequality(1)：
         -6 < x < -2/3

---

    The final solution set is :
         -6 < x < -2/3
