[ 1/1Inequality]
    Assignment:Find the solution set of inequality (12.5*x*x/(4-x*x)-3*x*x+2)/(25*x/(4-x*x)-5*x) >((15+x*x/2)*x*x*x/(4-x*x)+1.5*x*(1-x*x)/(4-x*x)+2*x/(4-x*x)+x*x+1)/((-5*x*x*(1-5/(4-x*x)))/(4-x*x)) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 12.5 * x * x / ( 4 - x * x ) - 3 * x * x + 2 ) / ( 25 * x / ( 4 - x * x ) - 5 * x ) > ( ( 15 + x * x / 2 ) * x * x * x / ( 4 - x * x ) + 1.5 * x * ( 1 - x * x ) / ( 4 - x * x ) + 2 * x / ( 4 - x * x ) + x * x + 1 ) / ( ( -5 * x * x * ( 1 - 5 / ( 4 - x * x ) ) ) / ( 4 - x * x ) )         (1)
        From the definition field of divisor
         4 - x * x ≠ 0        (2 )
        From the definition field of divisor
         4 - x * x ≠ 0        (3 )
        From the definition field of divisor
         25 * x / ( 4 - x * x ) - 5 * x ≠ 0        (4 )
        From the definition field of divisor
         4 - x * x ≠ 0        (5 )
        From the definition field of divisor
         4 - x * x ≠ 0        (6 )
        From the definition field of divisor
         4 - x * x ≠ 0        (7 )
        From the definition field of divisor
         4 - x * x ≠ 0        (8 )
        From the definition field of divisor
         4 - x * x ≠ 0        (9 )
        From the definition field of divisor
         ( -5 * x * x * ( 1 - 5 / ( 4 - x * x ) ) ) / ( 4 - x * x ) ≠ 0        (10 )
