    Assignment:Find the solution set of inequality (m-2)^2+4m-20 ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( m - 2 ) ^ 2 + 4 * m - 20 ≥0         (1)

---

    From inequality(1)：
         m ≤ -4 或  m ≥ 4

---

    The final solution set is :
         m ≤ -4 或  m ≥ 4
