[ 1/1Inequality]
    Assignment:Find the solution set of inequality sqrt(x^2+3x-4) >x+1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         sqrt ( x ^ 2 + 3 * x - 4 ) > x + 1         (1)
        From the definition field of √
         x ^ 2 + 3 * x - 4 ≥ 0        (2 )

    From inequality(1):
         x > 5
    From inequality(2):
         x ≤ -4 或  x ≥ 1

    From inequalities (1) and (2)
         x > 5    (3)

    The final solution set is :

         x > 5
