Question

What are the coordinates for the center of the circle and the length of the radius? x2 + y2 – x – 2y – 11/4 = 0

Answer 1

[x2-x+1/4]+[y2-2y+1]=(11/4)+(1/4)+1

Answer 2

(x-1/2)^2 + (y-1)^2 = 13

Answer 3

Woops, equals 4*

Answer 4

So your circle is centered at (1/2,1) with a radius of 2
