Assignment:Find the solution set of inequality x-5/(x+3)^2 >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x - 5 / ( x + 3 ) ^ 2 >0 (1)
From the definition field of divisor
x + 3 ≠ 0 (2 )
From inequality(1):
x > 0.425989
From inequality(2):
x < -3 或 x > -3
From inequalities (1) and (2)
x > 0.425989 (3)
The final solution set is :
x > 0.425989Your problem has not been solved here? Please take a look at the hot problems !
