Answer: Yes it could
Explanation:
The equation given is a circle. For an equation to represent equation of a circle, the following conditions must be met
1.) The coefficient of x² and y² must be the same
2) The equation must have a linear function containing x and y like AX and ???Y in the equation above.
Since the equation given conforms with the general of a circle x²+y²+2gx+2fy+c = 0, therefore the equation could represents a circle
