    Assignment:Find the solution set of inequality (2x+1)(x-1) ≥8(9-x)-1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * x + 1 ) * ( x - 1 ) ≥8 * ( 9 - x ) - 1         (1)

---

    From inequality(1)：
         x ≤ -8 或  x ≥ 9/2

---

    The final solution set is :
         x ≤ -8 或  x ≥ 9/2
