Factor:
\n" ); document.write( "\"36-49z%5E2\" Rewrite this as the difference of squares:
\n" ); document.write( "\"%286%29%5E2-%287z%29%5E2\" The difference of squares can be factored thusly:
\n" ); document.write( "\"A%5E2-B%5E2+=+%28A%2BB%29%28A-B%29\" so...
\n" ); document.write( "\"%286%29%5E2-%287z%29%5E2+=+highlight%28%286%2B7z%29%286-7z%29%29\"
\n" ); document.write( "
\n" );
