[ 1/1Inequality]
    Assignment:Find the solution set of inequality (x^2+5x+4)/(x-3) >= -2x .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x ^ 2 + 5 * x + 4 ) / ( x - 3 ) >= -2 * x         (1)
        From the definition field of divisor
         x - 3 ≠ 0        (2 )

---

    From inequality(1)：
         x ≥ 3
    From inequality(2)：
         x < 3 或  x ＞ 3

---

    From inequalities (1) and (2)
         x ＞ 3    (3)

---

    The final solution set is :
         x ＞ 3
