[ 1/1Inequality]
    Assignment:Find the solution set of inequality (k－3)^2－4(k－1) ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( k - 3 ) ^ 2 - 4 * ( k - 1 ) ≤0         (1)

---

    From inequality(1)：
         1.535898 ≤ k ≤ 8.464102

---

    The final solution set is :
         1.535898 ≤ k ≤ 8.464102
