    Assignment:Find the solution set of inequality 2*W^4-89*W^2+20.1 <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2 * W ^ 4 - 89 * W ^ 2 + 20.1 <0         (1)

---

    From inequality(1)：
         -6.653796 < W < -0.476446 或  0.476446 < W < 6.653796

---

    The final solution set is :
         -6.653796 < W < -0.476446 或  0.476446 < W < 6.653796
