    Assignment:Find the solution set of inequality （1-y）^2-4(2y-4)(3-3y) >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 - y ) ^ 2 - 4 * ( 2 * y - 4 ) * ( 3 - 3 * y ) >= 0         (1)

---

    From inequality(1)：
         y ≤ 1 或  y ≥ 49/25

---

    The final solution set is :
         y ≤ 1 或  y ≥ 49/25
