6x^2 +6y^2+48x+24y=30 what is the radius of the circle. What are the intercepts?

Question

I doubt that is a circle.

anonymous · Answer

transform the equation in a form$$(x-h)^2+(y-k)^2=r^2$$where (h,k) is the center of the circle and r is the radius... you can do it by completing the square of both x and y...

This is definitely a circle.  You have to complete the square on both the x and y terms, and then divide out the 6 on everything, but it is definitely a circle.

Plus what else could it be?  If it was an ellipse, the 6 coefficients couldn't be the same, they would have to be different numbers.  If A and B have the same sign and A does NOT equal B, then the equation may define an ellipse.  That's from my textbook...Teacher's addition.

I mean edition, not addition...math on the brain!
