Question

2x²- 2y²-x+y__________1-2x-2yСократить дробь​

Answer 1

2(x^2-y^2)-(x-y) 2(x+y)(x-y)-(x-y)

____________ = ____________ =

1-2x-2y 1-2x-2y

(2x+2y-1)(x-y)

= ___________ = -(x-y)=y-x

1-2x-2y

Answer 2

To simplify the expression (2x² - 2y² - x + y) / (1 - 2x - 2y), we can factor out common terms in the numerator and denominator and then cancel them out.

Numerator: 2x² - 2y² - x + y

We can rearrange the terms to group the common factors: (2x² - x) + (y - 2y²)

Factoring out the common factors: x(2x - 1) + y(1 - 2y)

Denominator: 1 - 2x - 2y

Now we can rewrite the expression as: (x(2x - 1) + y(1 - 2y)) / (1 - 2x - 2y)

This is the simplified form of the fraction.
