Find the difference. express your answer in simplest form. (5s/s^2-10s+25) - (25/s^2-10s+25)

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)
