[ 1/1Inequality]
Assignment:Find the solution set of inequality x+2/(x²-5x-6) >= 0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x + 2 / ( x ^ 2 - 5 * x - 6 ) >= 0 (1)
From the definition field of divisor
x ^ 2 - 5 * x - 6 ≠ 0 (2 )
From inequality(1):
-1.2258 ≤ x ≤ -1 或 x ≥ 0.27414
From inequality(2):
x < -1 或 -1 < x < 6 或 x > 6
From inequalities (1) and (2)
-1.2258 ≤ x < -1 或 0.27414 ≤ x < 6 或 x > 6 (3)
The final solution set is :
-1.2258 ≤ x < -1 或 0.27414 ≤ x < 6 或 x > 6Your problem has not been solved here? Please take a look at the hot problems !
