%283x%5E2%2B7x%2B2%29%2F%284x%5E2-16%29 Start with the given expression.


%28%28x%2B2%29%283x%2B1%29%29%2F%284x%5E2-16%29 Factor 3x%5E2%2B7x%2B2 to get %28x%2B2%29%283x%2B1%29.


%28%28x%2B2%29%283x%2B1%29%29%2F%284%28x-2%29%28x%2B2%29%29 Factor 4x%5E2-16 to get 4%28x-2%29%28x%2B2%29.

%283x%2B1%29%2F%284%28x-2%29%29 Simplify.


%283x%2B1%29%2F%284x-8%29 Distribute


So %283x%5E2%2B7x%2B2%29%2F%284x%5E2-16%29 simplifies to %283x%2B1%29%2F%284x-8%29.


In other words, %283x%5E2%2B7x%2B2%29%2F%284x%5E2-16%29=%283x%2B1%29%2F%284x-8%29
