To find the third term, use the formula $\"c+=+%28b%2F2%29%5E2\"$ :
\n" ); document.write( " $\"c+=+%281%2F2%29%5E2\"$
\n" ); document.write( " $\"c+=+1%2F4\"$ \r
\n" ); document.write( "\n" ); document.write( "The perfect square trinomial is $\"x%5E2+%2B+x+%2B+1%2F4\"$ . \n" ); document.write( "

\n" );
