Best ResponseYou've already chosen the best response.0k first divide eqn by 2 so that there is no coefficient of x^2 and y^2

Best ResponseYou've already chosen the best response.0what if I have a 2 in x^2 and a 3 in y^2?

Best ResponseYou've already chosen the best response.0i dont thnk thats possible bcoz coefficient of x^2 is always equal to coefficient of y^2 in a circle

Best ResponseYou've already chosen the best response.0nice. So after dividing the equation by 2 I got: x^2+y^24x+y14=0 what else should i do?

Best ResponseYou've already chosen the best response.0then compar with eqn x^2 +y^2 +2gfx+2hy+c=0 we see 4x=2gfx n 6y=2hy g=2 n h=3 centre(g,h) (2,3) n radius r^2=g^2 +h^2c r^2=4+9+14 r^2=27 r=3\[\sqrt{3}\]

Best ResponseYou've already chosen the best response.0Ok in the third line you state that 4x=2gfx and in the next g=2. how do you get rid of f?

Best ResponseYou've already chosen the best response.0According to what I understand, we have to leave x^2 and y^2 with coefficient 1. Is that correct?

Best ResponseYou've already chosen the best response.0Then we have to match the equation with x^2 +y^2 +2gfx+2hy+c=0.
