[ 1/1Inequality]
Assignment:Find the solution set of inequality -(5*k+6)+sqrt((6+5*k)^2-36+20k) <0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
-( 5 * k + 6 ) + sqrt ( ( 6 + 5 * k ) ^ 2 - 36 + 20 * k ) <0 (1)
From the definition field of √
( 6 + 5 * x ) ^ 2 - 36 + 20 * x ≥ 0 (2 )
From inequality(1):
k < 9/5
From inequality(2):
k ≤ -16/5 或 k ≥ 0
From inequalities (1) and (2)
k ≤ -16/5 或 0 ≤ k < 9/5 (3)
The final solution set is :
k ≤ -16/5 或 0 ≤ k < 9/5Your problem has not been solved here? Please take a look at the hot problems !
