[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1.5x+(2.5x*x*x/(4-x*x))-x*x+4 <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        1.5 * x + ( 2.5 * x * x * x / ( 4 - x * x ) ) - x * x + 4 <0         (1)
        From the definition field of divisor
         4 - x * x ≠ 0        (2 )

    From inequality(1):
         x < -3.439733 或  -2 < x < -1.093286 或  x > 2
    From inequality(2):
         x < -2 或  -2 < x < 2 或  x > 2

    From inequalities (1) and (2)
         x < -3.439733 或  -2 < x < -1.093286 或  x > 2    (3)

    The final solution set is :

         x < -3.439733 或  -2 < x < -1.093286 或  x > 2
