    Assignment:Find the solution set of inequality (197n+13.3n^2)*(197+20n^2)/(394+40n)+556*(2+n)-979-317n-1.2[(110n+4n^2)*(110n+2.6n^2)/(220+8n)+24*(14.5+n)+36*(11+n)+208*(7.4+n)+728*(2.7+n) ) >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 197 * n + 13.3 * n ^ 2 ) * ( 197 + 20 * n ^ 2 ) / ( 394 + 40 * n ) + 556 * ( 2 + n ) - 979 - 317 * n - 1.2 * ( ( 110 * n + 4 * n ^ 2 ) * ( 110 * n + 2.6 * n ^ 2 ) / ( 220 + 8 * n ) + 24 * ( 14.5 + n ) + 36 * ( 11 + n ) + 208 * ( 7.4 + n ) + 728 * ( 2.7 + n ) ) >= 0         (1)
        From the definition field of divisor
         394 + 40 * x ≠ 0        (2 )
        From the definition field of divisor
         220 + 8 * x ≠ 0        (3 )

---

    From inequality(1)：
         -14.76497 ≤ n ≤ -9.85 或  n ≥ 19.831214
    From inequality(2)：
         n < -197/20 或  n ＞ -197/20
    From inequality(3)：
         n < -55/2 或  n ＞ -55/2

---

    From inequalities (1) and (2)
         -14.76497 ≤ n < -197/20 或  n ≥ 19.831214    (4)
    From inequalities (3) and (4)
         -14.76497 ≤ n < -197/20 或  n ≥ 19.831214    (5)

---

    The final solution set is :
         -14.76497 ≤ n < -197/20 或  n ≥ 19.831214
