Explicación paso a paso:
1)(x + 1)² + (y + 9)² = 9
x² + 2x + 1 + y² + 18y + 81 = 9
x² + 2x + 1 + y² + 18y + 81 - 9 = 0
x² + 2x + y² + 18y + 1+ 81 - 9 = 0
x² + 2x + y² + 18y + 73 = 0
2) (x + 7)² + (y - 2)² = 49
X² + 14x + 49 + (y² - 4y + 4) = 49
X² + 14x + 49 + y² - 4y + 4 - 49 = 0
X² + 14x + y² - 4y + 4 = 0
3)(x - 3)² + (y + 12)² = 169
x² - 6x + 9 + y² + 24 y + 144 = 169
x² - 6x + 9 + y² + 24 y + 144 - 169 = 0
x² - 6x + y² + 24 y + 144 - 169 + 9 = 0
x² - 6x + y² + 24 y - 16 = 0
