Solve by completing the square:
\n" ); document.write( " $\"x%5E2+%2B+6x+%2B1+=+0\"$
\n" ); document.write( " $\"x%5E2%2B6x%2B____+=+-1\"$
\n" ); document.write( " $\"x%5E2%2B6x%2B%286%2F2%29%5E2=-1%2B%286%2F2%29%5E2\"$
\n" ); document.write( " $\"x%5E2%2B6x%2B9=-1%2B9+=8\"$
\n" ); document.write( " $\"%28x%2B3%29%5E2=8\"$
\n" ); document.write( " $\"sqrt%28x%2B3%29=sqrt%288%29\"$
\n" ); document.write( " $\"x%2B3=sqrt%288%29\"$
\n" ); document.write( " $\"x=-3%2B-sqrt%288%29\"$
\n" ); document.write( " $\"x=-3-sqrt%288%29\"$
\n" ); document.write( " $\"x=-3-2.83\"$

\n" ); document.write( "or;
\n" ); document.write( " $\"x=-3%2Bsqrt%288%29\"$
\n" ); document.write( " $\"x=-3%2B2.83\"$
\n" ); document.write( " $\"x=-.17\"$
