Question 2 Add: (x) x2 – y2 – 1, y2 – 1 – x2, 1 – x2 – y2 (x2 – y2 – 1) + (y2 – 1 – x2 ) + (1 – x2 – y2) = x2 – y2 – 1 + y2 – 1 – x2 + 1 – x2 – y2 = x2 – x2 – x2 – y2 + y2 – y2 – 1 – 1 + 1 = x2 (1 – 1 – 1) + y2 (–1 + 1 – 1) + (–1 – 1 + 1) = x2 (0 – 1) + y2 (0 – 1) + (–2 + 1) = x2 (–1) + y2 (–1) + (–1) = –x2 – y2 – 1
