$\"y=%2B-sqrt%289-%28x-4%29%5E2%29+-+2\"$
\n" ); document.write( "add 2 to get
\n" ); document.write( " $\"y+%2B+2+=+%2B-sqrt%289-%28x-4%29%5E2%29\"$
\n" ); document.write( "square both sides to get
\n" ); document.write( " $\"%28y%2B2%29%5E2+=+9-%28x-4%29%5E2\"$
\n" ); document.write( "add (x-4)^2 to both sides to get
\n" ); document.write( " $\"%28x-4%29%5E2+%2B+%28y%2B2%29%5E2+=+9\"$
\n" ); document.write( "center = (4,-2) with radius of 3 \n" ); document.write( "
