Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credi
Vikki [24]
The equation of the circle: (x-a)^2+(y-b)^2=r^2

where:
(a; b) - coordinates of the center
r - a radius

Use: (a\pm b)^2=a^2\pm2ab+b^2\ \ \ \ (*)

We have:

x^2-4x+y^2+8y=-4\\\\x^2-2x\cdot2+y^2+2y\cdot4=-4\ \ \ |add\ 2^2\ and\ 4^2\ to\ both\ sides\\\\\underbrace{x^2-2x\cdot2+2^2}_{(*)}+\underbrace{y^2+2y\cdot4+4^2}_{(*)}=-4+2^2+4^2\\\\(x-2)^2+(y+4)^2=-4+4+16\\\\(x+2)^2+(y-4)^2=16\\\\(x+2)^2+(y-4)^2=4^2

Answer:
The center: (-2; 4)
The radius: r = 4
