solve each equation by completing the square.
\n" ); document.write( "n^2+12n+37=2
\n" ); document.write( "(n^2+12n+36)-36+37=2
\n" ); document.write( "(n+6)^2=1
\n" ); document.write( "n+6=±√1=±1
\n" ); document.write( "n=-6±1
\n" ); document.write( "n=-7
\n" ); document.write( "or
\n" ); document.write( "n=-5
\n" ); document.write( "..
\n" ); document.write( "k^2+8k-47=7
\n" ); document.write( "(k^2+8k+16)-16-47=7
\n" ); document.write( "(k+4)^2=70
\n" ); document.write( "k+4=±√70
\n" ); document.write( "k=-4±√70
\n" ); document.write( "k=-4-√70≈-12.37
\n" ); document.write( "or
\n" ); document.write( "k=-4+√70≈4.37 \n" ); document.write( "
\n" );
