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