    Assignment:Find the solution set of inequality (651.4+25.4n^2)/(977.1+152.4n)+(2.1+n)*837.3+2082.64+323.8-1.2{[(50+3n)*(203n+7n^2)/(304.6+21.8n)]+(2.7+n)*930+(6+n)*241+(12+n)*29+(14+n)*10} >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 651.4 + 25.4 * n ^ 2 ) / ( 977.1 + 152.4 * n ) + ( 2.1 + n ) * 837.3 + 2082.64 + 323.8 - 1.2 * ( ( ( 50 + 3 * n ) * ( 203 * n + 7 * n ^ 2 ) / ( 304.6 + 21.8 * n ) ) + ( 2.7 + n ) * 930 + ( 6 + n ) * 241 + ( 12 + n ) * 29 + ( 14 + n ) * 10 ) >= 0         (1)
        From the definition field of divisor
         977.1 + 152.4 * x ≠ 0        (2 )
        From the definition field of divisor
         304.6 + 21.8 * x ≠ 0        (3 )

    From inequality(1)：
         n ≤ -14.057329 或  -13.972477 ≤ n ≤ -1.788655
    From inequality(2)：
         n < -6.411417 或  n ＞ -6.411417
    From inequality(3)：
         n < -13.972477 或  n ＞ -13.972477

---

    From inequalities (1) and (2)
         n ≤ -14.057329 或  -13.972477 ≤ n < -6.411417 或  -6.411417 < n ≤ -1.788655     (4)
    From inequalities (3) and (4)
         n ≤ -14.057329 或  -13.972477 < n < -6.411417 或  -6.411417 < n ≤ -1.788655     (5)

---

    The final solution set is :
         n ≤ -14.057329 或  -13.972477 < n < -6.411417 或  -6.411417 < n ≤ -1.788655
