    Assignment:Find the solution set of inequality 1160.57+88.178*n+（305.92*n+26.74*n^2）*(458.88*n+26.74*n^2)/(1835.52+160.44*n)-1.2*(69.03+4.87*n)*(208.59*n+9.74*n^2)/(29.22*n+417.18) ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1160.57 + 88.178 * n + ( 305.92 * n + 26.74 * n ^ 2 ) * ( 458.88 * n + 26.74 * n ^ 2 ) / ( 1835.52 + 160.44 * n ) - 1.2 * ( 69.03 + 4.87 * n ) * ( 208.59 * n + 9.74 * n ^ 2 ) / ( 29.22 * n + 417.18 ) ≥0         (1)
        From the definition field of divisor
         1835.52 + 160.44 * x ≠ 0        (2 )
        From the definition field of divisor
         29.22 * x + 417.18 ≠ 0        (3 )

---

    From inequality(1)：
         n ≥ -17.014773
    From inequality(2)：
         n < -11.440539 或  n ＞ -11.440539
    From inequality(3)：
         n < -14.277207 或  n ＞ -14.277207

---

    From inequalities (1) and (2)
         -17.014773 ≤ n < -11.440539 或  n ＞ -11.440539    (4)
    From inequalities (3) and (4)
         -17.014773 ≤ n < -14.277207 或  -14.277207 < n < -11.440539 或  n ＞ -11.440539    (5)

---

    The final solution set is :
         -17.014773 ≤ n < -14.277207 或  -14.277207 < n < -11.440539 或  n ＞ -11.440539
