$$x^2Bxy+y^2+6x+8y+F=0$$

precal · Answer

is there a plus sign in between x^2 and bxy?

anonymous · Answer

Yes. Thanks for pointing that out.

|dw:1368751243142:dw|

precal · Answer

well this is not a quadratic for starters, it is a conic and it is a circle to be precise

anonymous · Answer

Ok, I see that now. But I am still not quite sure exactly how changing B would effect the graph. How would the circle transform?

precal · Answer

It would move the center of the circle. I am taking a big guess.  You would need to complete the square to determine the center of the circle and its radius.
