To simplify ( (x + y)(x - y) ), you can use the distributive property, which states that ( (a + b)(c + d) = ac + ad + bc + bd ). Applying this property, you get ( x^2 - xy + xy - y^2 ). Simplifying further, ( x^2 - y^2 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
