\n" ); document.write( "2x^2+2y^2+4x-12y-22=0
\n" ); document.write( " x^2 + y^2 + 2x - 6y = 11 |completing the Squares
\n" ); document.write( " (x+1)^2 + (y-3)^2 = 11 + 1 + 9
\n" ); document.write( " (x+1)^2 + (y-3)^2 = 21
\n" ); document.write( "circle: C(-1,3) r = sqrt(21)
\n" ); document.write( " \n" ); document.write( "
