4m(4m - 3n²)We're asked to simplify the following expression:[tex]\sf 16m^2+(-12mn^2)[/tex]So, we start by distributing the minus sign:[tex]\sf 16m^2-12mn^2[/tex]Next, notice that both terms have a common factor of 4m, so, we can factor it out.Divide both terms by 4m. You're left with:[tex]\sf 4m-3n^2[/tex]Put 4m outside the parentheses:[tex]\sf 4m(4m-3n^2)[/tex]
