[ 1/1Inequality]
    Assignment:Find the solution set of inequality 4     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities:
        4 < x ^ 2 - x - 2         (1)
         x ^ 2 - x - 2 <10         (2)

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

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

    The final solution set is :

         -3 < x < -2 或  3 < x < 4
