Answer 2

Ответ:

- 3х + 1.

Пошаговое объяснение:

2x(x-1) - (2x-1)(x+1) = 2х^2 - 2х - (2х^2 + 2х - х - 1) = 2х^2 - 2х - 2х^2 - 2х + х + 1 = - 3х + 1.

Answer 3

To simplify the given expression and put it in standard form, let's expand the brackets and combine like terms:

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

Expanding the first bracket:

= 2x^2 - 2x

Expanding the second bracket:

= (2x - 1)(x + 1) = 2x(x + 1) - 1(x + 1) = 2x^2 + 2x - x - 1 = 2x^2 + x - 1

Now we can substitute these results back into the original expression and combine like terms:

2x(x - 1) - (2x - 1)(x + 1) = 2x^2 - 2x - (2x^2 + x - 1) = 2x^2 - 2x - 2x^2 - x + 1 = -3x + 1

Therefore, the expression 2x(x - 1) - (2x - 1)(x + 1) simplifies to -3x + 1 in standard form.
