    Assignment:Find the solution set of inequality 20000x^4+200x^2-2+sqrt(2) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        20000 * x ^ 4 + 200 * x ^ 2 - 2 + sqrt ( 2 ) <0         (1)

---

    From inequality(1)：
         -0.048663 < x < 0.048663

---

    The final solution set is :
         -0.048663 < x < 0.048663
