[ 1/1Inequality]
    Assignment:Find the solution set of inequality （X＋1）^(2)－4×（2x－1）×（x－4） >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( X + 1 ) ^ ( 2 ) - 4 × ( 2 * X - 1 ) × ( X - 4 ) >= 0         (1)

---

    From inequality(1)：
         3/7 ≤ X ≤ 5

---

    The final solution set is :
         3/7 ≤ X ≤ 5
