Question

Determine the general form of the equation for the circle (x – 1)2 + (y + 2)2 = 3.

x2 + y2 – 2x + 4y + 2 = 0

x2 + y2 – x + y + 3 = 0

x2 + y2 – 2x + 4y – 4 = 0

x2 + y2 – x + y + 2 = 0

Answer 1

(x-1)(x-1) + (y+2)(y+2) = 3

x2 -1x -1x + 1 + y2 +2y +2y +4=3

x2 +y2 -2x +4y + 2=0

A is the answer
