[ 1/1Inequality]
Assignment:Find the solution set of inequality x >1,x+1/x+16/x^2+1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x >1 , x + 1 / x + 16 / x ^ 2 + 1 (1)
From the definition field of divisor
x ≠ 0 (2 )
From the definition field of divisor
x ≠ 0 (3 )
From inequality(1):
x > 1
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < 0 或 x > 0
From inequalities (1) and (2)
x > 1 (4)
From inequalities (3) and (4)
x > 1 (5)
The final solution set is :
