[ 1/1Inequality]
    Assignment:Find the solution set of inequality (x^2+2x-6)/(x+2) >3 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( x ^ 2 + 2 * x - 6 ) / ( x + 2 ) >3         (1)
        From the definition field of divisor
         x + 2 ≠ 0        (2 )

    From inequality(1):
         -3 < x < -2 或  x > 4
    From inequality(2):
         x < -2 或  x > -2

    From inequalities (1) and (2)
         -3 < x < -2 或  x > 4    (3)

    The final solution set is :

         -3 < x < -2 或  x > 4
