Answer:

The answer is:


(5 x - 12)/((x + 3)(x - 3))

Explanation:


(3)/(x ^(2) - 9) + (5)/(x + 3)

First, we have to make the denorminator same by multiplying:


(3)/((x + 3)(x - 3)) + (5)/(x + 3)


(3)/((x + 3)(x - 3)) + (5(x - 3))/((x + 3)(x - 3))

Then, we can add up everything together:


(3 + 5x - 15)/((x + 3(x - 3))


(5x - 12)/((x + 3)(x - 3))

(Sorry if being messy)
