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