This is a difference of two squares which factors like this,
\n" ); document.write( "\"Z%5E2-A%5E2=%28Z%2BA%29%28Z-A%29\"
\n" ); document.write( "In this case,
\n" ); document.write( "\"Z%5E2=4x%5E2\"
\n" ); document.write( "\"Z=2x\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"A%5E2=49\"
\n" ); document.write( "\"A=7\"
\n" ); document.write( "So then,
\n" ); document.write( "\"4x%5E2-49=%282x-7%29%282x%2B7%29\"
\n" ); document.write( "
\n" );
