[ 1/1Inequality]
    Assignment:Find the solution set of inequality [(2x-5)(x+1)]/[(x+3)(x-2)] >3 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( ( 2 * x - 5 ) * ( x + 1 ) ) / ( ( x + 3 ) * ( x - 2 ) ) >3         (1)
        From the definition field of divisor
         ( x + 3 ) * ( x - 2 ) ≠ 0        (2 )

    From inequality(1):
         -7.690416 < x < -3 或  1.690416 < x < 2
    From inequality(2):
         x < -3 或  -3 < x < 2 或  x > 2

    From inequalities (1) and (2)
         -7.690416 < x < -3 或  1.690416 < x < 2     (3)

    The final solution set is :

         -7.690416 < x < -3 或  1.690416 < x < 2
