[ 1/1Inequality]
Assignment:Find the solution set of inequality [1/4+1-(1-a)^4] <{1+[1-(1-a)^4]*(8*a+8)/(a+2)}*1/4 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 1 / 4 + 1 - ( 1 - a ) ^ 4 ) < ( 1 + ( 1 - ( 1 - a ) ^ 4 ) * ( 8 * a + 8 ) / ( a + 2 ) ) * 1 / 4 (1)
From the definition field of divisor
x + 2 ≠ 0 (2 )
From inequality(1):
-2 < a < 0 或 0 < a < 2
From inequality(2):
a < -2 或 a > -2
From inequalities (1) and (2)
-2 < a < 0 或 0 < a < 2 (3)
The final solution set is :
-2 < a < 0 或 0 < a < 2 Your problem has not been solved here? Please take a look at the hot problems !
