Assignment:Find the solution set of inequality 0 <5t^2-6t <8 .
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities:
0 <5 * t ^ 2 - 6 * t (1)
5 * t ^ 2 - 6 * t <8 (2)
From inequality(1):
t < 0 或 t > 6/5
From inequality(2):
-4/5 < t < 2
From inequalities (1) and (2)
-4/5 < t < 0 或 6/5 < t < 2 (3)
The final solution set is :
-4/5 < t < 0 或 6/5 < t < 2 Your problem has not been solved here? Please take a look at the hot problems !
