Assignment:Find the solution set of inequality 2n/(n+2) >(3n-2)÷(2n-2) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 * n / ( n + 2 ) > ( 3 * n - 2 ) ÷ ( 2 * n - 2 ) (1)
From the definition field of divisor
x + 2 ≠ 0 (2 )
From inequality(1):
n < -2 或 0.535898 < n < 1 或 n > 7.464102
From inequality(2):
n < -2 或 n > -2
From inequalities (1) and (2)
n < -2 或 0.535898 < n < 1 或 n > 7.464102 (3)
The final solution set is :
n < -2 或 0.535898 < n < 1 或 n > 7.464102Your problem has not been solved here? Please take a look at the hot problems !
