[ 1/1Inequality]
Assignment:Find the solution set of inequality x^2-3x+2/x^2-2x-3 ≤0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x ^ 2 - 3 * x + 2 / x ^ 2 - 2 * x - 3 ≤0 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
0.596246 ≤ x ≤ 5.530613
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
0.596246 ≤ x ≤ 5.530613 (3)
The final solution set is :
0.596246 ≤ x ≤ 5.530613Your problem has not been solved here? Please take a look at the hot problems !
