Answer 2

To factor the expression M^2 + mn - 7m - 7n, we can look for common factors and grouping.

First, let's group the terms in pairs:

(M^2 + mn) - (7m + 7n)

Now, let's factor out common terms from each pair:

M(M + n) - 7(m + n)

Finally, we can factor out a common factor from both terms:

M(M + n) - 7(m + n)

Now, we can notice that both terms have a common factor of (m + n). So, we can factor it out:

(M - 7)(M + n)

Therefore, the factored expression is (M - 7)(M + n).
