Пошаговое объяснение:

2х-1+4х^2 +2х-2х-1=4х^2 +2х-1

Answer 2

To simplify the given expression, let's first distribute the term (2x-1) to the term (2x+1) inside the parentheses:

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

Now, use the distributive property to expand the second term:

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

= 2x - 1 + 4x^2 + 2x - 2x - 1

Next, combine like terms:

= 4x^2 + 2x - 2x - 1 - 1

= 4x^2 - 2

So, the simplified expression is:

4x^2 - 2
