$\"b-2+=+1%2F%28b+%2B+2%29\"$
\n" ); document.write( "or $\"%28b-2%29%28b%2B2%29=1\"$
\n" ); document.write( "or $\"b%5E2+-+2%5E2+=+1\"$
\n" ); document.write( "or $\"b%5E2+=+1%2B4+=+5\"$
\n" ); document.write( "Therefore either, $\"b+=+sqrt%285%29\"$ or $\"b+=+-sqrt%285%29\"$ \n" ); document.write( "

\n" );
