(x^(2)-y^(2))/(x+y)
The binomial can be factored using the difference of squares formula, because both terms are perfect squares. The difference of squares formula is a^(2)-b^(2)=(a-b)(a+b).
((x-y)(x+y))/(x+y)
Reduce the expression by canceling out the common factor of (x+y) from the numerator and denominator.
((x-y)(x+y))/((x+y))
Reduce the expression by canceling out the common factor of (x+y) from the numerator and denominator.
(x-y)
Remove the parentheses around the expression x-y.
x-y
