Question

(y + 2)^2 - 2y (y + 2) ​

Answer 1

Ответ:

y^2+4y+4-2y^2-4y=-y^2+4

Объяснение:

Answer 2

To simplify the expression $(y + 2)^2 - 2y(y + 2)$, you can factor out the common factor of $(y + 2)$:

$(y + 2)^2 - 2y(y + 2) = (y + 2)(y + 2) - 2y(y + 2)$

Now, you can factor out $(y + 2)$ from both terms:

$(y + 2)(y + 2 - 2y)$

Next, simplify the expression inside the parentheses:

$y + 2 - 2y$

Now, combine like terms:

$-y + 2$

So, the simplified expression is $-y + 2$.
