Question

Simplify 9x^2 - 25/3x-5

Answer 1

First, we are going to write it like this:
$\frac{9x^2-25}{3x-5}$
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:
$=\frac{\left(3x+5\right)\left(3x-5\right)}{3x-5}$
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!
