    Assignment:Find the solution set of inequality (326n+17n^2)*(326+25n^2)/(326+51n)+837*(2+n)-356n-657-1.2[(51n+3.6n^2)*(102n+2.4n^2)/(102+7n)+10.5*(14+n)+30*(12+n)+240*(6+n)+930*(2.7+n) ) >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 326 * n + 17 * n ^ 2 ) * ( 326 + 25 * n ^ 2 ) / ( 326 + 51 * n ) + 837 * ( 2 + n ) - 356 * n - 657 - 1.2 * ( ( 51 * n + 3.6 * n ^ 2 ) * ( 102 * n + 2.4 * n ^ 2 ) / ( 102 + 7 * n ) + 10.5 * ( 14 + n ) + 30 * ( 12 + n ) + 240 * ( 6 + n ) + 930 * ( 2.7 + n ) ) >= 0         (1)
        From the definition field of divisor
         326 + 51 * x ≠ 0        (2 )
        From the definition field of divisor
         102 + 7 * x ≠ 0        (3 )

    From inequality(1)：
         -19.284495 ≤ n ≤ -14.799312 或  -14.571429 ≤ n ≤ -6.392157 或  n ≥ 12.305059
    From inequality(2)：
         n < -6.392157 或  n ＞ -6.392157
    From inequality(3)：
         n < -102/7 或  n ＞ -102/7

---

    From inequalities (1) and (2)
         -19.284495 ≤ n ≤ -14.799312 或  -14.571429 ≤ n < -6.392157 或  n ≥ 12.305059    (4)
    From inequalities (3) and (4)
         -19.284495 ≤ n ≤ -14.799312 或  -102/7 < n < -6.392157 或  n ≥ 12.305059    (5)

---

    The final solution set is :
         -19.284495 ≤ n ≤ -14.799312 或  -102/7 < n < -6.392157 或  n ≥ 12.305059
