[ 1/1Inequality]
    Assignment:Find the solution set of inequality (3x²+2x+1)/(x²+x+2) <= 1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 3 * x ^ 2 + 2 * x + 1 ) / ( x ^ 2 + x + 2 ) <= 1         (1)
        From the definition field of divisor
         x ^ 2 + x + 2 ≠ 0        (2 )

    From inequality(1):
         -1 ≤ x ≤ 1/2
    From inequality(2):
         x ∈ R (R为全体实数),即在实数范围内,不等式恒成立!

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

    The final solution set is :

         -1 ≤ x ≤ 1/2
