Assignment:Find the solution set of inequality (x^2-9)/(x-2) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( x ^ 2 - 9 ) / ( x - 2 ) >0 (1)
From the definition field of divisor
x - 2 ≠ 0 (2 )
From inequality(1):
-3 < x < 2 或 x > 3
From inequality(2):
x < 2 或 x > 2
From inequalities (1) and (2)
-3 < x < 2 或 x > 3 (3)
The final solution set is :
-3 < x < 2 或 x > 3Your problem has not been solved here? Please take a look at the hot problems !
