Answer 2

To simplify the expression:

(3/(x² - 9) - 1/(x - 3)) * (x² + 6x + 9)/5

First, we need to factor the denominators and simplify the fractions. The expression can be rewritten as follows:

(3/[(x - 3)(x + 3)] - 1/(x - 3)) * [(x + 3)(x + 3)]/5

Now, let's find a common denominator for the fractions:

The common denominator for the first part is (x - 3)(x + 3), and for the second part, it's 5.

So, we can rewrite the expression as:

[3 - (x - 3)] / [(x - 3)(x + 3)] * [(x + 3)(x + 3)] / 5

Now, simplify:

[3 - (x - 3)] = 3 - x + 3 = 6 - x

So, the expression simplifies to:

(6 - x) / 5

That's the simplified form of the expression.
