To find the third term, use the formula $\"%28b%2F2%29%5E2\"$ :
\n" ); document.write( " $\"c+=+%28-12%2F2%29%5E2\"$
\n" ); document.write( " $\"c+=+%28-6%29%5E2\"$
\n" ); document.write( " $\"c+=+36\"$ \r
\n" ); document.write( "\n" ); document.write( "The perfect square trinomial is $\"x%5E2+-+12x+%2B+36\"$ . \n" ); document.write( "

\n" );
