№7: Сократить (x^2-4x+4) / (2x^2-6x+4)

To simplify the expression (x^2-4x+4) / (2x^2-6x+4), we can factorize the numerator and denominator and then cancel out any common factors.

The numerator can be factored as (x-2)^2, and the denominator can be factored as (x-2)(2x-2).

Now, we can cancel out the common factor (x-2) from the numerator and denominator:

(x^2-4x+4) / (2x^2-6x+4) = (x-2)^2 / (x-2)(2x-2)

Canceling out the common factor (x-2), we get:

(x-2) / (2x-2)

So, the simplified expression is (x-2) / (2x-2).
