Assignment:Find the solution set of inequality 20/x+10/(x-2) = 35x >4 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
20 / x + 10 / ( x - 2 ) 35 * x >4 (1)
From the definition field of divisor
x ≠ 0 (2 )
From the definition field of divisor
x - 2 ≠ 0 (3 )
From inequality(1):
x > 0
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < 2 或 x > 2
From inequalities (1) and (2)
x > 0 (4)
From inequalities (3) and (4)
0 < x < 2 或 x > 2 (5)
The final solution set is :
0 < x < 2 或 x > 2Your problem has not been solved here? Please take a look at the hot problems !
