    Assignment:Find the solution set of inequality 6.46/[1.44x*x-10.56x+18.64] ≥-1.5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        6.46 / ( 1.44 * x * x - 10.56 * x + 18.64 ) ≥ -1.5         (1)
        From the definition field of divisor
         1.44 * x * x - 10.56 * x + 18.64 ≠ 0        (2 )

---

    From inequality(1)：
         x ≤ 2.95956 或  x ≥ 4.373773
    From inequality(2)：
         x < 2.95956 或  2.95956 < x < 4.373773 或  x ＞ 4.373773

---

    From inequalities (1) and (2)
         x < 2.95956 或  x ＞ 4.373773    (3)

---

    The final solution set is :
         x < 2.95956 或  x ＞ 4.373773
