alright, so i'm having some trouble with the general form of a circle. i know that it's basically x2+y2+ax+by+c=0 , but this problem is giving me a hard time... 1. The problem statement, all variables and given/known data a circle has the equasion 4x2+4y2+24x-16y-48=0. graph the cirlce using the center (h,k) and radius R. find the intercepts, if any. ... so, don't you combine all the like terms together first? so it would be: (4x2+24x)2+(4y2-16y2)=48 but then what? or did i already screw it up?
