[ 1/1Inequality]
    Assignment:Find the solution set of inequality (-2-p-sqrt((2+p)＾2-4)/2 ) <= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( -2 - p - sqrt ( ( 2 + p ) ^ 2 - 4 ) / 2 ) <= 0         (1)
        From the definition field of √
         ( 2 + x ) ^ 2 - 4 ≥ 0        (2 )

---

    From inequality(1)：
         p ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         p ≤ -4 或  p ≥ 0

---

    From inequalities (1) and (2)
         p ≤ -4 或  p ≥ 0    (3)

---

    The final solution set is :
         p ≤ -4 或  p ≥ 0
