Hello again so... upon trying to find the center and radius of this equation: x^2+y^26x8y+16=0
I find that the center is (3,4)
When finding the radius and inputing so many forms out of fustration I keep on coming up with 9 ! I have to submit my homework online so it tells me automatically if it is right or wrong and so far it is wrong. I literally asked a question like this 12 days ago and I guess I still don't understand what to do when I get to this point. HELP !
