    Assignment:Find the solution set of inequality W^4-44.5*W^2+20.2 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         W ^ 4 - 44.5 * W ^ 2 + 20.2 >0         (1)

---

    From inequality(1)：
         W < -6.636365 或  -0.677244 < W < 0.677244 或  W ＞ 6.636365

---

    The final solution set is :
         W < -6.636365 或  -0.677244 < W < 0.677244 或  W ＞ 6.636365
