Answer 1

Explicación paso a paso:

$(am - an - 3)( m - {n}^{2} ) \\ = (am - an - 3)( m ) - (am - an - 3)( {n}^{2} ) \\ = a {m}^{2} - amn - 3m - ( am {n}^{2} - a {n}^{3} - 3 {n}^{2} ) \\ = a {m}^{2} - amn - 3m - am {n}^{2} + a {n}^{3} + 3 {n}^{2} \\ = - am {n}^{2}+ a {n}^{3} + a {m}^{2} - amn+ 3 {n}^{2}- 3m$
