[ 1/1Inequality]
    Assignment:Find the solution set of inequality （2x-5）^(2)+（3x+1）^(2) >13（x^(2)-10） .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * x - 5 ) ^ ( 2 ) + ( 3 * x + 1 ) ^ ( 2 ) >13 * ( x ^ ( 2 ) - 10 )         (1)

---

    From inequality(1)：
         x < 78/7

---

    The final solution set is :
         x < 78/7
