[ 1/1Inequality]
    Assignment:Find the solution set of inequality (197n+20n^2)*(394n+40n^2)/(591+120n)+1045+556n-1.2[(55n+4n^2)*(219n+7.48n^2)/(329+23n)+1972+723n+1551+208n+343+30n+346+24n] >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 197 * n + 20 * n ^ 2 ) * ( 394 * n + 40 * n ^ 2 ) / ( 591 + 120 * n ) + 1045 + 556 * n - 1.2 * ( ( 55 * n + 4 * n ^ 2 ) * ( 219 * n + 7.48 * n ^ 2 ) / ( 329 + 23 * n ) + 1972 + 723 * n + 1551 + 208 * n + 343 + 30 * n + 346 + 24 * n ) >0         (1)
        From the definition field of divisor
         591 + 120 * x ≠ 0        (2 )
        From the definition field of divisor
         329 + 23 * x ≠ 0        (3 )

    From inequality(1):
         -14.304348 < n < -12.444312 或  -4.925 < n < -3.490381 或  n > 9.328415
    From inequality(2):
         n < -197/40 或  n > -197/40
    From inequality(3):
         n < -14.304348 或  n > -14.304348

    From inequalities (1) and (2)
         -14.304348 < n < -12.444312 或  -4.925 < n < -3.490381 或  n > 9.328415    (4)
    From inequalities (3) and (4)
         -14.304348 < n < -12.444312 或  -4.925 < n < -3.490381 或  n > 9.328415    (5)

    The final solution set is :

         -14.304348 < n < -12.444312 或  -4.925 < n < -3.490381 或  n > 9.328415
