16x%5E2+%2B+y%5E2+%2B+32x+%2B+4y++-++12+=+0
+y%5E2+%2B+4y++=+-16x%5E2+-32x+%2B12+.........complete square on left side
+%28y%5E2+%2B+4y%2Bb%5E2%29-b%5E2++=+-16x%5E2+-32x+%2B12+
+%28y%5E2+%2B+4y%2B2%5E2%29-2%5E2++=+-16x%5E2+-32x+%2B12+
+%28y%2B2%29%5E2-4++=+-16x%5E2+-32x+%2B12+
+%28y%2B2%29%5E2=+-16x%5E2+-32x+%2B12%2B4+
+%28y%2B2%29%5E2=+-16x%5E2+-32x+%2B16+
+y%2B2=+sqrt%28-16x%5E2+-32x+%2B16+%29
+y=+sqrt%28-16x%5E2+-32x+%2B16+%29-2
