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
