12:25 rn but never too late for a TL maths video to drop!

Quick question: can you do as level maths stats and mechanics videos for Edexcel?

I appreciate this method of solving the problem but there's another one that makes use of the general equation of circle i.e. x^2 + y^2 + 2gx + 2fy + c = 0 where g, f and c are unknown constants, substitute all the three points in the general equation to get three new equations and solve them to find g, f and c. The values of g, f and c are then substituted in the general equation of the circle to get the desired equation
