You can put this solution on YOUR website!
(5m - 6n + 7)(2m - 3n - 4)\r
\n" ); document.write( "\n" ); document.write( "to multiply out this term we use a method known as foiling. You multiply each term in the first equation by each term in the second equation.
\n" ); document.write( "I will break this down step by step.
\n" ); document.write( "Take 5m and multiply it.
\n" ); document.write( "5m(2m - 3n - 4)
\n" ); document.write( "10m^2-15mn-20m (hold onto this we will use it later.)
\n" ); document.write( "now -6n\r
\n" ); document.write( "\n" ); document.write( "-6n(2m - 3n - 4)
\n" ); document.write( "-12mn+18n^2+24n(hold onto this we will use it later.)
\n" ); document.write( "now we will multiply out 7.
\n" ); document.write( "7(2m - 3n - 4)
\n" ); document.write( "14m-21n-28\r
\n" ); document.write( "\n" ); document.write( "You now take all the results from the foil process and line them up.\r
\n" ); document.write( "\n" ); document.write( "10m^2-15mn-20m-12mn+18n^2+24n+14m-21n-28\r
\n" ); document.write( "\n" ); document.write( "you combine all like terms
\n" ); document.write( "10m^2+18n^2-27mn-6m+3n-28\r
\n" ); document.write( "\n" ); document.write( "this is your answer
\n" ); document.write( "\"10m%5E2%2B18n%5E2-27mn-6m%2B3n-28\"
