[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0.5x^2 ≥0.75x(7/4)-3.5x-(5/4) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.5 * x ^ 2 ≥0.75 * x * ( 7 / 4 ) - 3.5 * x - ( 5 / 4 )         (1)

---

    From inequality(1)：
         x ≤ -3.699173 或  x ≥ -0.675827

---

    The final solution set is :
         x ≤ -3.699173 或  x ≥ -0.675827
