Answer 2

To simplify the expression (10/a-5) + (20a)/(25-a^2) + 2, we'll start by finding the common denominator and combining the fractions.

First, let's simplify each term individually:

1. (10/a-5) can be simplified by multiplying both the numerator and denominator by (a-5): (10/a-5) = (10(a-5)/(a-5)) = (10(a-5))/(a-5) = 10

2. (20a)/(25-a^2) cannot be simplified further.

Now, we can combine the simplified fractions:

10 + (20a)/(25-a^2) + 2 = 10 + 2 + (20a)/(25-a^2)

Simplifying further:

10 + 2 + (20a)/(25-a^2) = 12 + (20a)/(25-a^2)

The final simplified expression is 12 + (20a)/(25-a^2).
