    Assignment:Find the solution set of inequality xx+2*(2^0.5)x-30 <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x * x + 2 * ( 2 ^ 0.5 ) * x - 30 <0         (1)

---

    From inequality(1)：
         -√50 < x < √18

---

    The final solution set is :
         -√50 < x < √18
