Question

Сократить дробь 5a-5y ___________ 25a 2) 8m-2n ____________ 12m+6n 3) 25x-9y _____________ 5x+3y 4) y^2-4y+4 ____________ y-2

Answer 1

1) 5а и 25а сокращаем =-5у/5а
2) 8m и 12 m, 2n и 6n сокращаем =2m/3m+3n
3) 25х и 5х, 9у и 3у сокращаем=5х-3у/1
4) незнаю

Answer 2

1. To simplify the fraction (5a-5y)/(25a), we can factor out a common factor of 5 from the numerator: (5(a-y))/(25a)

Next, we can simplify the fraction further by canceling out the common factor of 5 in the numerator and denominator: (a-y)/(5a)

Therefore, the simplified form of the fraction is (a-y)/(5a).

2. To simplify the fraction (8m-2n)/(12m+6n), we can factor out a common factor of 2 from the numerator and denominator: (2(4m-n))/(6(2m+n))

Now, we can simplify the fraction by canceling out the common factor of 2 in the numerator and denominator: (4m-n)/(3(2m+n))

So, the simplified form of the fraction is (4m-n)/(3(2m+n)).

3. To simplify the fraction (25x-9y)/(5x+3y), no common factors can be factored out from the numerator and denominator. So, the fraction remains as it is: (25x-9y)/(5x+3y)

The fraction (25x-9y)/(5x+3y) cannot be simplified any further.

4. To simplify the fraction (y^2-4y+4)/(y-2), we can factor the numerator as a perfect square trinomial: ((y-2)(y-2))/(y-2)

Now, we can simplify the fraction by canceling out the common factor of (y-2) in the numerator and denominator: (y-2)/(1)

Therefore, the simplified form of the fraction is (y-2)/1, which is equivalent to y-2.
