[ 1/1Inequality]
    Assignment:Find the solution set of inequality (((-2/27)x^3+(4/9)x^2+(13/9)x-(56/27))/2)^2+(((-1/3)x^2+(4/3)x-(19/3))/3)^3 <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( ( -2 / 27 ) * x ^ 3 + ( 4 / 9 ) * x ^ 2 + ( 13 / 9 ) * x - ( 56 / 27 ) ) / 2 ) ^ 2 + ( ( ( -1 / 3 ) * x ^ 2 + ( 4 / 3 ) * x - ( 19 / 3 ) ) / 3 ) ^ 3 <0         (1)

---

    From inequality(1)：
         x < 15/4 或  x ＞ 15/4

---

    The final solution set is :
         x < 15/4 或  x ＞ 15/4
