[ 1/1Inequality]
Assignment:Find the solution set of inequality (5x+1)/(x^2+x+1) >2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 5 * x + 1 ) / ( x ^ 2 + x + 1 ) >2 (1)
From the definition field of divisor
x ^ 2 + x + 1 ≠ 0 (2 )
From inequality(1):
1/2 < x < 1
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)
1/2 < x < 1 (3)
The final solution set is :
1/2 < x < 1 Your problem has not been solved here? Please take a look at the hot problems !
