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