[ 1/1Inequality]
Assignment:Find the solution set of inequality 1/x-2/x^2 >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1 / x - 2 / x ^ 2 >0 (1)
From the definition field of divisor
x ≠ 0 (2 )
From the definition field of divisor
x ≠ 0 (3 )
From inequality(1):
x > 2
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < 0 或 x > 0
From inequalities (1) and (2)
x > 2 (4)
From inequalities (3) and (4)
x > 2 (5)
The final solution set is :
