You can put this solution on YOUR website!
You did a great job with the start of the equations, you just need to keep going.
\n" ); document.write( "First equation: m^3-mn^2, you found the gcf and factored it,
\n" ); document.write( "leaving: m(m^2 - n^2). Now you need to factor (m^2 - n^2). It is the difference of perfect squares. It factors to (m + n)(m - n).
\n" ); document.write( "So, m^3-mn^2 factors to m(m + n)(m - n).
\n" ); document.write( "Next equation: mn^2 + m^2n - 2m^3. You found the gcf and factored,
\n" ); document.write( "leaving m(n^2 + mn - 2m2). Look at only what is inside the parenthesis. You need to factor that (do reverse foil). You get (n - m)(n + 2m). Double check to make sure that when you do FOIL, it gives you (n^2 + mn - 2m2). So, now
\n" ); document.write( "mn^2 + m^2n - 2m^3 simplifies to m(n - m)(n + 2m). \n" ); document.write( "
\n" );
