[ 1/1Inequality]
Assignment:Find the solution set of inequality 4sqrt(m)十2m十2 ≥18 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
4 * sqrt ( m ) + 2 * m + 2 ≥18 (1)
From the definition field of √
x ≥ 0 (2 )
From inequality(1):
m ≥ 4
From inequality(2):
m ≥ 0
From inequalities (1) and (2)
m ≥ 4 (3)
The final solution set is :
m ≥ 4Your problem has not been solved here? Please take a look at the hot problems !
