@satellite73 ive had a long day at work and im kinda not functioning that well, can u take up on this one?

anonymous · Answer

lol

anonymous · Answer

$$x^2-9=0$$
$$(x-3)(x+3)-0$$
$x=3$ or $x=-3$

anonymous · Answer

for $x^2-9<0$ it will be all values of $x$ between the zeros, that is any $x$ that satisfies $$-3<x<3$$

anonymous · Answer

for $x^2-9>0$ it is everything else

anonymous · Answer

So x<-3 or x>3
