Given: $f(x)=x^{2}+8 x+16$

1. Solve for $x$ if $f(x)>0$
2. For which values of $p$ will $f(x)=p$ have TWO unequal negative roots?

\begin{array}{r}
x^{2}+8 x+16>0 \\
(x+4)(x+4)>0
\end{array}

The function values remain positive $x \in R, x \neq-4$

x \in R, x \neq-4 \quad \text { or } \\
x \in(-\infty ;-4) \text { or } x \in(-4 ; \infty) \text { or } \\
x<-4 \text { or } x>-4
