Answer 1

To solve this problem you must apply the proccedure shown below:

1. You have the following expression:

(5s/s^2-10s+25) - (25/s^2-10s+25)

2. As you can see, they have the same denominator, therefore, you can rewrite it as below:

(5s-25)/ (25/s^2-10s+25)

3. When you factor ir, you obtain:

5(s-25)/(s-5)(s-5)

3. Simplifying:

5/(s-5)
