    Answer:

     \small \sf \: ( m - n ) ( a + b )

    Step-by-step explanation:

    ( am – an + bm – bn)

    • Do the grouping

    = ( am – an ) + ( bm – bn )

    • Factor out a in the first and b in the second group

    = a ( m – n ) + b ( m – n )

    • factor out common term m – n by using distributive property

    = ( m – n ) ( a + b )
