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

    From inequality(1):
         x < -3.561553 或  x > 0.561553
    From inequality(2):
         x ≤ -3 或  x ≥ 0

    From inequalities (1) and (2)
         x < -3.561553 或  x > 0.561553    (3)

    The final solution set is :

         x < -3.561553 或  x > 0.561553
