%28%28%28x%5E2-4%29%29%2Fx%29%2F%28%28%284x-8%29%29%2Fx%29
= %28highlight%28%28x%5E2-4%29%29%2Fx%29%2F%28highlight%28%284x-8%29%29%2Fx%29=%28%28x%2B2%29%28x-2%29%2Fx%29%2F%28%284%28x-2%29%29%2Fx%29
This means numerator divided by the denominator. During division, we multiply the numerator by the multiplicative inverse of the denominator. So
= %28%28%28x%2B2%29%28x-2%29%29%2Fx%29%2A%28x%2F%284%28x-2%29%29%29

= %28%28x%2B2%29%28x-2%29x%29%2F%28x%2A4%28x-2%29%29 =

= %28%28x%2B2%29%29%2F4 Answer.

I hope this is clear to you.
