[ 1/1Inequality]
Assignment:Find the solution set of inequality x+2+1/(2*x) >-2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x + 2 + 1 / ( 2 * x ) > -2 (1)
From the definition field of divisor
2 * x ≠ 0 (2 )
From inequality(1):
-3.870829 < x < -0.129171 或 x > 0
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
-3.870829 < x < -0.129171 或 x > 0 (3)
The final solution set is :
-3.870829 < x < -0.129171 或 x > 0Your problem has not been solved here? Please take a look at the hot problems !
