Question

What is the equation of this circle in general form?

x² + y² + 8x + 10y + 25 = 0

x2+y2−8x−10y+25=0

x2+y2−8x−10y+37=0

x² + y² + 8x + 10y + 37 = 0

Answer 1

Tis the actual answer :)

Answer 2

The center of the circle is located at (-4,-5) and its radius is 4.
The equation of a circle is:

`(x - xo) {}^(2) + (y - yo) {}^(2) = r {}^(2)`
(x+4)²+(y+5)²=4²
x²+8x+16+y²+10y+25=16
Simplify 16:
x²+y²+8x+10y+25=0
