Assignment:Find the solution set of inequality 3/(36x^2-24x-5) <0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
3 / ( 36 * x ^ 2 - 24 * x - 5 ) <0 (1)
From the definition field of divisor
36 * x ^ 2 - 24 * x - 5 ≠ 0 (2 )
From inequality(1):
-0.166667 < x < 0.833333
From inequality(2):
x < -1/6 或 -1/6 < x < 5/6 或 x > 5/6
From inequalities (1) and (2)
-0.166667 < x < 0.833333 (3)
The final solution set is :
-0.166667 < x < 0.833333 Your problem has not been solved here? Please take a look at the hot problems !
