If $\"a=n\"$ then, $\"b=n%2B2\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"b%5E2-a%5E2=%28n%2B2%29%5E2-n%5E2\"$
\n" ); document.write( " $\"b%5E2-a%5E2=%28n%5E2%2B4n%2B4%29-n%5E2\"$
\n" ); document.write( " $\"b%5E2-a%5E2=4n%2B4\"$
\n" ); document.write( " $\"b%5E2-a%5E2=4%28n%2B1%29\"$
\n" ); document.write( " $\"b%5E2-a%5E2=4b\"$
