# How do you solve -5/(x+3)^2>0 using a sign chart?

Apr 7, 2018

#### Explanation:

Let $f \left(x\right) = - \frac{5}{x + 3} ^ 2$

The domainof definition is $I = \left(- \infty , - 3\right) \cup \left(- 3 , + \infty\right)$

The question asks for $f \left(x\right) > 0$

$\forall x \in I , f \left(x\right) < 0$

There are no solutions to this inequality
