Assignment:Find the solution set of inequality sqrt(4+24a) >4a-2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
sqrt ( 4 + 24 * a ) >4 * a - 2 (1)
From the definition field of √
4 + 24 * x ≥ 0 (2 )
From inequality(1):
a < 5/2
From inequality(2):
a ≥ -1/6
From inequalities (1) and (2)
-1/6 ≤ a < 5/2 (3)
The final solution set is :
-1/6 ≤ a < 5/2Your problem has not been solved here? Please take a look at the hot problems !
