Answer 1

Answer:

We can factorise it mn+m+n+1 as

=m(n+1)+1(n+1)

=(m+1)(n+1)

Therefore, factors are (m+1)(n+1)

Answer 2

Answer:

( m - 1 )( n - 1 )

Step-by-step explanation:

mn - m - n + 1

Taking m common in first 2 term and - 1 in last 2 terms

= m( n - 1 ) - 1( n - 1 )

= ( m - 1 )( n - 1 )
