If the coefficient in front of X and Y in the general equation of circle is not 1, what kind of equation is it? For example: 6x ^ 2 + 4Y ^ 2-6x = 0 There is also a linear term x in the formula, which should not be an ellipse

If the coefficients of quadratic terms are the same, the equation of circle is the same. If the coefficients of quadratic terms are different, it is an ellipse
