I believe it's the second one! Not one hundred percent sure - but I strongly believe it is!
I hope all is well, and you do okay on the test! (:
![f(x)=x^2-9 , g(x)=x^2-7x+12](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2-9%20%2C%20g%28x%29%3Dx%5E2-7x%2B12)
We need to find ![\frac{f}{g}(x)](https://tex.z-dn.net/?f=%5Cfrac%7Bf%7D%7Bg%7D%28x%29)
![\frac{f}{g}(x)=\frac{f(x)}{g(x)}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%7D%7Bg%7D%28x%29%3D%5Cfrac%7Bf%28x%29%7D%7Bg%28x%29%7D)
We replace f(x) and g(x)
![\frac{f}{g}(x)=\frac{f(x)}{g(x)}=\frac{x^2-9}{x^2-7x+12}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%7D%7Bg%7D%28x%29%3D%5Cfrac%7Bf%28x%29%7D%7Bg%28x%29%7D%3D%5Cfrac%7Bx%5E2-9%7D%7Bx%5E2-7x%2B12%7D)
Now factor the numerator and denominator and simplify it
![\frac{x^2-9}{x^2-7x+12}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2-9%7D%7Bx%5E2-7x%2B12%7D)
![\frac{(x+3)(x-3)}{(x-3)(x-4)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B3%29%28x-3%29%7D%7B%28x-3%29%28x-4%29%7D)
