Question:

This equation can be represented by which graph in the visual provided? $1732_w180_h20.png$

A A
Explaination

Rearrange the given equation so that the squares can be completed and the radius and center of the circle can be found: $4401_w179_h20.png$, divide each b coefficient by 2, square the value and add it to both sides so that the left hand side can be rewritten in terms of two binomial expressions: $7420_w303_h20.png$, which can be written as $5311_w187_h20.png$ The radius is $3460_w65_h19.png$, and the center is (-2, 1)
