Answer:

x/x+3

Step-by-step explanation:

first off, we start by factorizing.

we start with the numerator  taking x out making it x (x-3) / x^2 - 9

then we factorize the denominator a bit more...making it x (x-3) /  (x-3) (x+3)

as you can tell there is a (x-3) on both sides. so we can cross them out.

x/x+3 is left. try it yourself again so you can understand other questions like this! I hope I could help!
