    Assignment:Find the solution set of inequality X^4+X^3+X2^1+1 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         X ^ 4 + X ^ 3 + X * 2 ^ 1 + 1 >0         (1)

---

    From inequality(1)：
         X < -1.55898 或  X ＞ -0.472213

---

    The final solution set is :
         X < -1.55898 或  X ＞ -0.472213
