a) This is the equation of a circle. We can rewrite it as:(x+2)^2 + y^2 = 4This is a circle centered at (-2,0) with a radius of 2.
b) This is the equation of a circle. We can rewrite it as:(x+5)^2 + (y-4)^2 = 5This is a circle centered at (-5,4) with a radius of √5.
a) This is the equation of a circle. We can rewrite it as:
(x+2)^2 + y^2 = 4
This is a circle centered at (-2,0) with a radius of 2.
b) This is the equation of a circle. We can rewrite it as:
(x+5)^2 + (y-4)^2 = 5
This is a circle centered at (-5,4) with a radius of √5.
