%28a-1%29%2F%284a%29-%282a%2B3%29%2Fa Start with the given expression.


%28a-1%29%2F%284a%29-%284%282a%2B3%29%29%2F%284a%29 Multiply the second fraction by 4%2F4


%28a-1%29%2F%284a%29-%288a%2B12%29%2F%284a%29 Distribute.


%28%28a-1%29-%288a%2B12%29%29%2F%284a%29 Combine the fractions (this is only possible since the denominators are equal).


%28a-1-8a-12%29%2F%284a%29 Distribute.


%28-7a-13%29%2F%284a%29 Combine like terms.


So %28a-1%29%2F%284a%29-%282a%2B3%29%2Fa=%28-7a-13%29%2F%284a%29
