Question

X-3y/x^2-9y^2ав+а^2/а^2​

Answer 1

x-3y / x²-9y²= x-3y / (x-3y)(x+3y)= 1/ (x+3y)

ab+a² / a²= a(b+a)/ a²= a+b/ a= 1+ b/a

Answer 2

To simplify the given expression, let's first factor the denominators:

1. x^2 - 9y^2 = (x + 3y)(x - 3y)
2. a^2 - a^2 = 0

Now, the expression becomes:

X - 3y / (x + 3y)(x - 3y) + a^2 / 0

However, we have an issue here since division by zero is undefined. Therefore, the expression is not valid as it contains a division by zero.

If there's any typo or missing information in the original expression, please provide the correct expression, and I'll be happy to help simplify it for you.
