I just helped someone with this a couple days ago, so this should be easy :)

The first one is asking you- Something Squared minus 25 equals -9

anonymous · Answer

Your equation $$n^2-25=-9$$

anonymous · Answer

Now you have to solve for n

$\large\color{blue}{ \rm n^2-25=-9 }$ 

 $\large\color{blue}{ \rm n^2-25+9=-9 +9}$

 $\large\color{blue}{ \rm n^2-16=0}$

 $\large\color{blue}{ \rm (n-4)(n+4)=0}$ 

 $\large\color{blue}{ \rm n=~±~4}$

How would you graph that?
