Answer:
Step-by-step explanation:
hello :
x²+ y² + 6x - 4y - 27 = 0 means : (x²+6x+9)-9+(y²-4y+4)-4-27 =0
(x+3)²+(y-2)² = 40....standard form when the center is (-3 , 2) and radius √40
The center is (-3, 2), and the radius root40.
We have given
x²+ y² + 6x - 4y - 27 = 0
It can be written as
(x²+6x+9)-9+(y²-4y+4)-4-27 =0
Write the given equation in standard form
(x-a)^2+(y-b)^2=r^2
Where (a,b) be the center and
r-is the radius of the circle
(x+3)²+(y-2)² = 40
Compare the above equation with the standard form of the equation
The center is (-3, 2), and the radius root40.
