First, we are going to write it like this:

(9x^2-25)/(3x-5)
Then, we are going to do something like factoring, but it's not factoring. An example would be:
x^2-y^2=\left(x+y\right)\left(x-y\right)
If we apply it, we would be left with:

=(\left(3x+5\right)\left(3x-5\right))/(3x-5)
We cancel the common factors, and we are left with:

=3x+5
That's our final answer.

Let me know if you need any more help!
Thanks!
