Simplify each expression. state any excluded values. show your work. 1. 2p-24/4p-48 2. b^2+8b+15/b+5 3. 5-4n/4n-5

To solve this problem you must apply the proccedure shown below:
 1. 2p-24/4p-48
  - You must divide the numerator and the denominator by 2:
 p-12/2p-24

 2. b^2+8b+15/b+5
 - You must factor the numerator, as following:
 (b+3)(b+5)/(b+5)
 b+3

3. 5-4n/4n-5 
 Factor the negative sign (-), as following:
 -(4n-5)/(4n-5)
 -1
