Answer :
x² + y² = 45
x² - x² + y² = 45 - x²
y² = 45 - x²
y = 3√(5) - x
x² + (3√(5) - x)² = 45
x² + 45 - x² = 45
x² - x² + 45 = 45
0x² + 45 = 45
-45 -45
0x² = 0
0 0
x² = 0
x = 0
(0)² + y² = 45
0 + y² = 45
-0 -0
y² = 45
y = 3√5
(x y) = (0, 3√5)
x² - x² + y² = 45 - x²
y² = 45 - x²
y = 3√(5) - x
x² + (3√(5) - x)² = 45
x² + 45 - x² = 45
x² - x² + 45 = 45
0x² + 45 = 45
-45 -45
0x² = 0
0 0
x² = 0
x = 0
(0)² + y² = 45
0 + y² = 45
-0 -0
y² = 45
y = 3√5
(x y) = (0, 3√5)
