The simplified expression of (x + y)(x - y) is x^2 - y^2
<h3>How to solve the expression?</h3>
The expression is given as:
(x + y)(x - y)
Expand the bracket
x(x - y) + y(x -y)
Further, expand
x^2 - xy + xy - y^2
Evaluate the like terms
x^2 - y^2
Hence, the simplified expression of (x + y)(x - y) is x^2 - y^2
