Assignment:Find the solution set of inequality 1700/x >2(1700/(x+1)) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1700 / x >2 * ( 1700 / ( x + 1 ) ) (1)
From the definition field of divisor
x ≠ 0 (2 )
From the definition field of divisor
x + 1 ≠ 0 (3 )
From inequality(1):
x < -1 或 0 < x < 1
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < -1 或 x > -1
From inequalities (1) and (2)
x < -1 或 0 < x < 1 (4)
From inequalities (3) and (4)
x < -1 或 0 < x < 1 (5)
The final solution set is :
x < -1 或 0 < x < 1 Your problem has not been solved here? Please take a look at the hot problems !
