Assignment:Find the solution set of inequality (4x+2)/(3x-1) >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 4 * x + 2 ) / ( 3 * x - 1 ) >0 (1)
From the definition field of divisor
3 * x - 1 ≠ 0 (2 )
From inequality(1):
x < -1/2 或 x > 0.333333
From inequality(2):
x < 1/3 或 x > 1/3
From inequalities (1) and (2)
x < -1/2 或 x > 0.333333 (3)
The final solution set is :
x < -1/2 或 x > 0.333333Your problem has not been solved here? Please take a look at the hot problems !
