[ 1/1Inequality]
    Assignment:Find the solution set of inequality （1428.30+593.79*x+212.89*x^2+11.5*x^3）/(2449.62+661.7312*x+12.74*x^2+23/18*x^3) >1.2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1428.30 + 593.79 * x + 212.89 * x ^ 2 + 11.5 * x ^ 3 ) / ( 2449.62 + 661.7312 * x + 12.74 * x ^ 2 + 23 / 18 * x ^ 3 ) >1.2         (1)
        From the definition field of divisor
         2449.62 + 661.7312 * x + 12.74 * x ^ 2 + 23 / 18 * x ^ 3 ≠ 0        (2 )

---

    From inequality(1)：
         x < -20.446434 或  -3.878807 < x < -2.430748 或  x ＞ 3.050894
    From inequality(2)：
         x < -3.878807 或  x ＞ -3.878807

---

    From inequalities (1) and (2)
         x < -20.446434 或  -3.878807 < x < -2.430748 或  x ＞ 3.050894    (3)

---

    The final solution set is :
         x < -20.446434 或  -3.878807 < x < -2.430748 或  x ＞ 3.050894
