[ 1/1Inequality]
Assignment:Find the solution set of inequality 3/x+3 >x-4/x .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
3 / x + 3 > x - 4 / x (1)
From the definition field of divisor
x ≠ 0 (2 )
From the definition field of divisor
x ≠ 0 (3 )
From inequality(1):
x < -1.541381 或 0 < x < 4.541381
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < 0 或 x > 0
From inequalities (1) and (2)
x < -1.541381 或 0 < x < 4.541381 (4)
From inequalities (3) and (4)
x < -1.541381 或 0 < x < 4.541381 (5)
The final solution set is :
x < -1.541381 或 0 < x < 4.541381 Your problem has not been solved here? Please take a look at the hot problems !
