[ 1/1Inequality]
    Assignment:Find the solution set of inequality (1+1-(1-a)^9*(117*a*a+261*a+18)/(19*a*a+6*a+3))/9 <(1+(1-(1-a)^6)*(24*a+10)/(3*a+2))/6 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 + 1 - ( 1 - a ) ^ 9 * ( 117 * a * a + 261 * a + 18 ) / ( 19 * a * a + 6 * a + 3 ) ) / 9 < ( 1 + ( 1 - ( 1 - a ) ^ 6 ) * ( 24 * a + 10 ) / ( 3 * a + 2 ) ) / 6         (1)
        From the definition field of divisor
         19 * x * x + 6 * x + 3 ≠ 0        (2 )
        From the definition field of divisor
         3 * x + 2 ≠ 0        (3 )

    From inequality(1)：
         a < -2.292423 或  -0.050205 < a < 1.902498
    From inequality(2)：
         a ∈ R （R为全体实数），即在实数范围内，不等式恒成立！
    From inequality(3)：
         a < -2/3 或  a ＞ -2/3

---

    From inequalities (1) and (2)
         a < -2.292423 或  -0.050205 < a < 1.902498     (4)
    From inequalities (3) and (4)
         a < -2.292423 或  -0.050205 < a < 1.902498     (5)

---

    The final solution set is :
         a < -2.292423 或  -0.050205 < a < 1.902498
