[ 1/1Inequality]
    Assignment:Find the solution set of inequality (2x-5)(2x-5) >= (4x+7)(4x+7) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * x - 5 ) * ( 2 * x - 5 ) >= ( 4 * x + 7 ) * ( 4 * x + 7 )         (1)

---

    From inequality(1)：
         -6 ≤ x ≤ -1/3

---

    The final solution set is :
         -6 ≤ x ≤ -1/3
