Answer 3

You've provided two algebraic expressions, and it seems like you want to simplify them. Let's simplify each of them one by one:

1. (a² - b²) / (a + b)

This expression can be simplified using the difference of squares factorization, which is a² - b² = (a + b)(a - b):

(a² - b²) / (a + b) = [(a + b)(a - b)] / (a + b)

Now, you can cancel out the common factor of (a + b) in the numerator and denominator:

= (a - b)

So, the simplified expression is (a - b).

2. (a - b) / (a² - b²)

In this case, we can factor the denominator using the difference of squares factorization, which is a² - b² = (a + b)(a - b):

(a - b) / (a² - b²) = (a - b) / [(a + b)(a - b)]

Now, you can cancel out the common factor of (a - b) in the numerator and denominator:

= 1 / (a + b)

So, the simplified expression is 1 / (a + b).
