Answer
True
Work Step by Step
Recall:
Conjugate pairs can be formed by changing the sign between the two terms, such as x+y to x-y.
The difference of two perfect squares can be factored as the product of conjugate pairs.
The difference of two perfect squares can be written as $x^{2}-y^{2}$
$$x^{2}-y^{2}=(x+y)(x-y)$$ Therefore, it is true.
