[ 1/1Inequality]
    Assignment:Find the solution set of inequality (1+a%)(1+2a%)大于等于((5+a)%+1) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 + a % ) * ( 1 + 2 * a % ) ≥ ( ( 5 + a ) % + 1 )         (1)

---

    From inequality(1)：
         a ≤ -102.440442 或  a ≥ √20845157/√3500000

---

    The final solution set is :
         a ≤ -102.440442 或  a ≥ √20845157/√3500000
