Answer:
Step-by-step explanation:
(x-1)² + (y+2)² = 3
-----------------------------
(x-1)²
(x-1)(x-1)
x² - x - x + 1
x² - 2x + 1
-------------------------------------
(y+2)²
(y+2)(y+2)
y²+ 2y + 2y + 4
y² + 4y + 4
---------------------------------------
(x² - 2x + 1) + (y² + 4y + 4) = 3
x² - 2x + 1 + y² + 4y + 4 = 3
x² + y² - 2x + 4y + 1 + 4 = 3
x² + y² - 2x + 4y + 5 = 3
x² + y² - 2x + 4y + 5 - 3 = 0
x² + y² - 2 x + 4y + 2 = 0
