[ 1/1Inequality]
Assignment:Find the solution set of inequality (1/m^2)+12m+2 <0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 1 / m ^ 2 ) + 12 * m + 2 <0 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
m < -1/2
From inequality(2):
m < 0 或 m > 0
From inequalities (1) and (2)
m < -1/2 (3)
The final solution set is :
m < -1/2Your problem has not been solved here? Please take a look at the hot problems !
