[ 1/2Inequality]
Assignment:Find the solution set of inequality (k-3/k-1)^2-4/k-1 ≤ 0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( k - 3 / k - 1 ) ^ 2 - 4 / k - 1 ≤ 0 (1)
From the definition field of divisor
x ≠ 0 (2 )
From the definition field of divisor
x ≠ 0 (3 )
From inequality(1):
1.294783 ≤ k ≤ 3.369306
From inequality(2):
k < 0 或 k > 0
From inequality(3):
k < 0 或 k > 0
From inequalities (1) and (2)
1.294783 ≤ k ≤ 3.369306 (4)
From inequalities (3) and (4)
1.294783 ≤ k ≤ 3.369306 (5)
The final solution set is :
1.294783 ≤ k ≤ 3.369306[2/2 Digtal analysis]
Work:Break 0 into prime factors.
