Assignment:Find the solution set of inequality (x+7)/(8-2x) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( x + 7 ) / ( 8 - 2 * x ) >0 (1)
From the definition field of divisor
8 - 2 * x ≠ 0 (2 )
From inequality(1):
-7 < x < 4
From inequality(2):
x < 4 或 x > 4
From inequalities (1) and (2)
-7 < x < 4 (3)
The final solution set is :
-7 < x < 4 Your problem has not been solved here? Please take a look at the hot problems !
