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

    From inequality(1):
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2):
         k ≤ -4.828427 或  k ≥ 0.828427

    The final solution set is :

        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
