Solution

We know that the general form of quadratic equation is $a x^{2} + b x + c = 0$ .

The given equation is $x^{2} - y^{2} = 0$ in which there are two variables $x$ and $y$ and therefore it is not of the form $a x^{2} + b x + c = 0$ .

Hence, the equation $x^{2} - y^{2} = 0$ is not a quadratic equation.
