Assignment:Find the solution set of inequality -8 <-8/x <-4 .
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities:
-8 < -8 / x (1)
-8 / x < -4 (2)
From the definition field of divisor
x ≠ 0 (3 )
From inequality(1):
x < 0 或 x > 1
From inequality(2):
0 < x < 2
From inequality(3):
x < 0 或 x > 0
From inequalities (1) and (2)
1 < x < 2 (4)
From inequalities (3) and (4)
1 < x < 2 (5)
The final solution set is :
1 < x < 2 Your problem has not been solved here? Please take a look at the hot problems !
