how do you find the center and radius of a circle?
Find the center of the circle given in general form (x^2)+(y^2)-10x-2y+50=49
You should group the terms as follows :
The terms in parenthesis on the LHS of the equation factor as perfect squares. On the right side, you'll have the radius value squared.
Can you continue from here?
EDIT: Please refer to my first post. I fixed an error I found in it.
