    Assignment:Find the solution set of inequality （x-2×x+x-2×x+x×x） <48 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x - 2 × x + x - 2 × x + x × x ) <48         (1)

---

    From inequality(1)：
         -6 < x < 8

---

    The final solution set is :
