\n" ); document.write( "You are not completing the square correctly. The standard form of the equation for the circle should have (x-3)^2 and (y-6)^2....

\n" ); document.write( "\"x%5E2+%2B+y%5E2+-+6x+-+12y+%2B+41+=+0\"
\n" ); document.write( "\"x%5E2-6x%2B9+%2B+y%5E2-12y%2B36+=+-41%2B9%2B36\"
\n" ); document.write( "\"%28x-3%29%5E2+%2B+%28y-6%29%5E2+=+4\"

\n" ); document.write( "The circle has center (3,6) and radius 2.

\n" ); document.write( "The distance from the origin to the center of the circle, by the Pythagorean Theorem, is sqrt(45) = 3*sqrt(5); since the radius of the circle is 2, the shortest distance from the origin to a point on the circle is 3*sqrt(5)-2.
