[ 1/1Inequality]
Assignment:Find the solution set of inequality (x^2-2)/(x+4) ≥-3x+10 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( x ^ 2 - 2 ) / ( x + 4 ) ≥ -3 * x + 10 (1)
From the definition field of divisor
x + 4 ≠ 0 (2 )
From inequality(1):
-4 ≤ x ≤ -7/2 或 x ≥ 3
From inequality(2):
x < -4 或 x > -4
From inequalities (1) and (2)
-4 < x ≤ -7/2 或 x ≥ 3 (3)
The final solution set is :
-4 < x ≤ -7/2 或 x ≥ 3Your problem has not been solved here? Please take a look at the hot problems !
