Question

1 - 2x + x^2_________x²-1 ​

Answer 1

Ответ:

(х-1)/(х+1)

Объяснение:

(х-1)²/(х-1)(х+1)=(х-1)/(х+1)

Answer 2

To simplify the expression (1 - 2x + x^2)/(x^2 - 1), we can factor both the numerator and the denominator.

The numerator can be factored as (1 - x)(1 - x).

The denominator can be factored using the difference of squares formula: x^2 - 1 = (x - 1)(x + 1).

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

Next, we can cancel out the common factors in the numerator and denominator: (1 - x)/(x + 1).

Therefore, the simplified form of (1 - 2x + x^2)/(x^2 - 1) is (1 - x)/(x + 1).
