[ 1/1Inequality]
Assignment:Find the solution set of inequality (4-2*(2k-1))/(2k-1) >= 2k-1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 4 - 2 * ( 2 * k - 1 ) ) / ( 2 * k - 1 ) >= 2 * k - 1 (1)
From the definition field of divisor
2 * x - 1 ≠ 0 (2 )
From inequality(1):
k ≤ -√5/2 或 0.5 ≤ k ≤ √5/2
From inequality(2):
k < 1/2 或 k > 1/2
From inequalities (1) and (2)
k ≤ -√5/2 或 1/2 < k ≤ √5/2 (3)
The final solution set is :
k ≤ -√5/2 或 1/2 < k ≤ √5/2 Your problem has not been solved here? Please take a look at the hot problems !
