First find:
+x%5E2+%2F+y%5E2+=+%28+r%5E2+%2B+2r%2As+%2B+s%5E2+%29+%2F+s%5E2+
+x%5E2+%2F+y%5E2+=+%28+r+%2B+s+%29%5E2+%2F+s%5E2+
-----------------
Take the square root of both sides. Since they say
+x%3E0+ and +y%3E0+, they want positive square roots,
not negative roots
---------------------
+x%2Fy+=+%28+r%2Bs+%29+%2F+s+
or, what is the same:
+x%2Fy+=+r%2Fs+%2B+1+
