Answer 1

Ответ:

ОТВЕТ: 3х + у²

РЕШЕНИЕ:

Объяснение:

2х²-х(2х-5у)-у(2х-у) = 2х²-2х²+5ху-2ху-у² = 3х + у²

Answer 2

Ответ:

2x²-2x²+5xy-2xy+y² = 3xy+y²

Answer 3

To simplify the given expression $2x^2 - x(2x - 5y) - y(2x - y)$, you can start by distributing the terms inside the parentheses and then combine like terms. Here's the step-by-step simplification:

$2x^2 - x(2x - 5y) - y(2x - y)$

Expand the terms inside the parentheses:

$2x^2 - (2x^2 - 5xy) - (2xy - y^2)$

Now, distribute the negative sign in front of the parentheses:

$2x^2 - 2x^2 + 5xy - 2xy + y^2$

Combine like terms:

$0x^2 + 3xy + y^2$

The simplified expression is $3xy + y^2$.
