Answer 1

Ответ:

1) 2(-a+b)

2) ???

3) 5(-m+2)

4) n(-3+n)

5) 7(-2x-3y+4)

6) m(-a+m-3b)

7) 4a(a+3b-4c)

8) 3y(-5x+3z-3y)

Answer 2

1. -2a + 2b: The common factor here is 2, so we can factor it out: 2(-a + b).

2. re xd: There doesn't appear to be a common factor that can be factored out in this expression.

3. -5m - 10: The common factor here is -5, so we can factor it out: -5(m + 2).

4. -3n + n²: There doesn't appear to be a common factor that can be factored out in this expression.

5. -14x - 21y + 28: The common factor here is -7, so we can factor it out: -7(2x + 3y - 4).

6. -am + m² - 3bm: The common factor here is -m, so we can factor it out: -m(a - m + 3b).

7. 4a² + 12ab - 16ac: The common factor here is 4a, so we can factor it out: 4a(a + 3b - 4c).

8. -15xy + 3yz - 9y²: The common factor here is -3y, so we can factor it out: -3y(5x - z + 3y).
