\n" ); document.write( "\"mn-5n%5E2-m%2B5n\" Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28mn-5n%5E2%29%2B%28-m%2B5n%29\" Group like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"n%28m-5n%29-1%28m-5n%29\" Factor out the GCF of \"n\" out of the first group. Factor out the GCF of \"-1\" out of the second group\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28n-1%29%28m-5n%29\" Since we have a common term of \"m-5n\", we can combine like terms\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"mn-5n%5E2-m%2B5n\" factors to \"%28n-1%29%28m-5n%29\"
\n" ); document.write( "
\n" );
