[ 1/1Inequality]
    Assignment:Find the solution set of inequality -t²＋t＋0.25 ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -t ^ 2 + t + 0.25 ≤0         (1)

---

    From inequality(1)：
         t ≤ -0.207107 或  t ≥ 1.207107

---

    The final solution set is :
         t ≤ -0.207107 或  t ≥ 1.207107
