%2815a%2B35%29%2F%2812a%5E2%2B28a%29 Start with the given expression.


%285%283a%2B7%29%29%2F%2812a%5E2%2B28a%29 Factor 15a%2B35 to get 5%283a%2B7%29.


%285%283a%2B7%29%29%2F%284a%283a%2B7%29%29 Factor 12a%5E2%2B28a to get 4a%283a%2B7%29.


%285%2Ahighlight%28%283a%2B7%29%29%29%2F%284a%2Ahighlight%28%283a%2B7%29%29%29 Highlight the common terms.


%285%2Across%28%283a%2B7%29%29%29%2F%284a%2Across%28%283a%2B7%29%29%29 Cancel out the common terms.


5%2F%284a%29 Simplify.


So %2815a%2B35%29%2F%2812a%5E2%2B28a%29 simplifies to 5%2F%284a%29.


In other words, %2815a%2B35%29%2F%2812a%5E2%2B28a%29=5%2F%284a%29
