☆2 inequalities
[ 1/2Inequality]
Assignment:Find the solution set of inequality m-sqrt(4m^2-10m+4) >= 1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
m - sqrt ( 4 * m ^ 2 - 10 * m + 4 ) >= 1 (1)
From the definition field of √
4 * x ^ 2 - 10 * x + 4 ≥ 0 (2 )
From inequality(1):
m ≤ 2.21525
From inequality(2):
m ≤ 1/2 或 m ≥ 2
From inequalities (1) and (2)
m ≤ 1/2 或 2 ≤ m ≤ 2.21525 (3)
The final solution set is :
m ≤ 1/2 或 2 ≤ m ≤ 2.21525[ 2/2Inequality]
Assignment:Find the solution set of inequality 4m^2-10m+4 >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
4 * m ^ 2 - 10 * m + 4 >0 (1)
From inequality(1):
m < 1/2 或 m > 2
The final solution set is :
m < 1/2 或 m > 2Your problem has not been solved here? Please take a look at the hot problems !
