[ 1/1Inequality]
Assignment:Find the solution set of inequality 3x-5x^2/(10x-3) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
3 * x - 5 * x ^ 2 / ( 10 * x - 3 ) >0 (1)
From the definition field of divisor
10 * x - 3 ≠ 0 (2 )
From inequality(1):
0 < x < 0.3 或 x > 9/25
From inequality(2):
x < 3/10 或 x > 3/10
From inequalities (1) and (2)
0 < x < 0.3 或 x > 9/25 (3)
The final solution set is :
0 < x < 0.3 或 x > 9/25Your problem has not been solved here? Please take a look at the hot problems !
