[ 1/1Inequality]
    Assignment:Find the solution set of inequality (4x^2-x-3)/(2x^2-x-3) <= 1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 4 * x ^ 2 - x - 3 ) / ( 2 * x ^ 2 - x - 3 ) <= 1         (1)
        From the definition field of divisor
         2 * x ^ 2 - x - 3 ≠ 0        (2 )

---

    From inequality(1)：
         -1 ≤ x ≤ 0 或  0 ≤ x ≤ 0 或  0 ≤ x ≤ 1.5
    From inequality(2)：
         x < -1 或  -1 < x < 3/2 或  x ＞ 3/2

---

    From inequalities (1) and (2)
         -1 < x ≤ 0 或  0 ≤ x ≤ 0 或  0 ≤ x < 3/2    (3)

---

    The final solution set is :
         -1 < x ≤ 0 或  0 ≤ x ≤ 0 或  0 ≤ x < 3/2
