Complete the square to find the center of the circle,
\n" ); document.write( " $\"2x%5E2+%2B+2y%5E2+%2B+10x+%96+6y+%96+55+=+0\"$
\n" ); document.write( " $\"2x%5E2%2B10x%2B2y%5E2-6y-55=0\"$
\n" ); document.write( " $\"x%5E2%2B5x%2By%5E2-3y-55%2F2=0\"$
\n" ); document.write( " $\"%28x%5E2%2B5x%2B25%2F4%29%2B%28y%5E2-3y%2B9%2F4%29-55%2F2-25%2F4-9%2F4=0\"$
\n" ); document.write( " $\"%28x%2B5%2F2%29%5E2%2B%28y-3%2F2%29%5E2=110%2F4%2B25%2F4%2B9%2F4\"$

\n" ); document.write( "The circle is centered at ( $\"-5%2F2\"$ , $\"3%2F2\"$ ) so it is $\"5%2F2\"$ from the y-axis.
