Question

              2 а) 4(m-n)+4m(m-n)

Answer 1

1) выносим общий множитель (m-n)

2) свободный член вносим в другую скобку (4+4m )

3) получаем  (m-n)(4+4m)

Answer 2

It seems you have provided a mathematical expression:

2a) 4(m - n) + 4m(m - n)

To simplify this expression, you can use the distributive property to expand the terms:

2a) 4m - 4n + 4m^2 - 4mn

Now, combine like terms:

2a) (4m + 4m^2) - (4n + 4mn)

Factor out the common factors from each group:

2a) 4m(1 + m) - 4n(1 + m)

Now, both terms have a common factor of (1 + m), so you can factor that out:

2a) 4(1 + m)(m - n)

So, the simplified expression is 4(1 + m)(m - n).
