You want THIS kind of form: \"%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Start with Completing the Squares for the x and y.
\n" ); document.write( "\"x%5E2%2B10x%2B25%2By%5E2-18y%2B81=49%2B25%2B81\"
\n" ); document.write( "\"%28x%2B5%29%5E2%2B%28y-9%29%5E2=155\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "radius r=(155)^(1/2)
\n" ); document.write( "Center is (-5,9).
\n" ); document.write( "
