Factor the following polynomial completely.

- x2y2 + x4 + 9 y2 - 9 x2

( x + 3)( x - 3)( x + y )( x - y )
( x - 3)( x - 3)( x + y )( x - y )
( x + 3)( x + 3)( x + y )( x - y )

Answer 1

Answer: A) (x + 3)(x - 3)(x + y)(x - y)

Explanation:

The correct factorization of the polynomial -x^2y^2 + x^4 + 9y^2 - 9x^2 is:

(x + 3)(x - 3)(x + y)(x - y)

This factorization is obtained by grouping terms and factoring out common factors.
