\"x%5E2%2By%5E2-6x%2B2y-6=0\"
\n" ); document.write( ":\r
\n" ); document.write( "\n" ); document.write( "\"%28x%5E2-6x%2B9%29%2B%28y%5E2%2B2y%2B1%29-6-9-1=0\"setting up to complete squares on x an y terms
\n" ); document.write( ":
\n" ); document.write( "\"%28x-3%29%5E2%2B%28y%2B1%29%5E2=16\"
\n" ); document.write( ":
\n" ); document.write( "so the center is at (3,-1)
\n" ); document.write( ":
\n" ); document.write( "D is the answer
