What is the general equation of the circle (x - 6)² + (y-6)² = 49?
A. x² + y²- 12x - 12y + 23 = 0
B. x²+y²-12x+12y+23=0
C. x² + y² + 12x - 12y +23=0
D. x²+y²-12x-12y-23=0​


Sagot :

Answer:

(x - 6)² + (y-6)² = 49

(x²-6x-6x+36)+(y²-6y-6y+36)=49

x²-12x+36+y²-6y+36=49

x²+y²-12x-12y+36+36=49

x²+y²-12x-12y+72=49

x²+y²-12x-12y+72-49=0

x²+y²-12x-12y+23=0

a. x²+y²-12x-12y+23=0
