What is the center of a circle whose equation is x^2+y^2-12x-2y+12=0
Answers: 1
.
denote the center of this circle (where 
and 
are to be found.) If the radius of this circle is 
, the equation of this circle would be:
.
.
describe the same circle. Therefore, corresponding coefficients of the two equations should match one another:
term should match in the two equations. Therefore: 
.The coefficient of the 
term should also match in the two equations. Therefore: 
.
and 
and 
.
