Question

2) (x + y) -(x - y):​

Answer 1

Ответ:

x² - y² ( * ) 2y ( - )

Объяснение:

(x + y) * (x - y) = x² + xy - xy - y² = x² - y²

(x + y) - (x - y) = 2y

Answer 2

Объяснение:

(х+у)-(х-у) = х+у-х+у=2у

Answer 3

To simplify the expression (x + y) - (x - y), you can use the distributive property and combine like terms:

(x + y) - (x - y)

First, distribute the negative sign (-) into the second parentheses:

(x + y) - x + y

Now, you can combine like terms by adding or subtracting them:

x - x cancels out because they are additive inverses, leaving you with:

y + y

Combine the y terms:

2y

So, the simplified expression is 2y.
