[ 1/1Inequality]
    Assignment:Find the solution set of inequality sqrt(x^2-6x+5) ≥x-2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         sqrt ( x ^ 2 - 6 * x + 5 ) ≥ x - 2         (1)
        From the definition field of √
         x ^ 2 - 6 * x + 5 ≥ 0        (2 )

    From inequality(1):
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2):
         x ≤ 1 或  x ≥ 5

    From inequalities (1) and (2)
         x ≤ 1 或  x ≥ 5    (3)

    The final solution set is :

         x ≤ 1 或  x ≥ 5
