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