[ 1/1Inequality]
    Assignment:Find the solution set of inequality -2     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities:
        -2 < x ^ 2 - 3 * x         (1)
         x ^ 2 - 3 * x ≤10         (2)

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

    From inequalities (1) and (2)
         -2 ≤ x < 1 或  2 < x ≤ 5     (3)

    The final solution set is :

         -2 ≤ x < 1 或  2 < x ≤ 5
