    Assignment:Find the solution set of inequality -6479.32-308.53*n+（399.37*n+18.82*n^2）*(1149.11*n+37.63*n^2)/(2396.19+112.89*n)-1.2*(97.74+4.87*n)*(312.97*n+9.74*n^2)/(29.22*n+586.44) ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -6479.32 - 308.53 * n + ( 399.37 * n + 18.82 * n ^ 2 ) * ( 1149.11 * n + 37.63 * n ^ 2 ) / ( 2396.19 + 112.89 * n ) - 1.2 * ( 97.74 + 4.87 * n ) * ( 312.97 * n + 9.74 * n ^ 2 ) / ( 29.22 * n + 586.44 ) ≥0         (1)
        From the definition field of divisor
         2396.19 + 112.89 * x ≠ 0        (2 )
        From the definition field of divisor
         29.22 * x + 586.44 ≠ 0        (3 )

---

    From inequality(1)：
         -31.060333 ≤ n ≤ -5.365327 或  n ≥ 6.199213
    From inequality(2)：
         n < -21.225884 或  n ＞ -21.225884
    From inequality(3)：
         n < -20.069815 或  n ＞ -20.069815

---

    From inequalities (1) and (2)
         -31.060333 ≤ n < -21.225884 或  -21.225884 < n ≤ -5.365327 或  n ≥ 6.199213    (4)
    From inequalities (3) and (4)
         -31.060333 ≤ n < -21.225884 或  -21.225884 < n < -20.069815 或  -20.069815 < n ≤ -5.365327 或  n ≥ 6.199213    (5)

---

    The final solution set is :
         -31.060333 ≤ n < -21.225884 或  -21.225884 < n < -20.069815 或  -20.069815 < n ≤ -5.365327 或  n ≥ 6.199213
