$$- 6 x^{2} + 4 x y - y^{2}$$
The perfect square
Let's highlight the perfect square of the square three-member
$$- 6 x^{2} + \left(x 4 y - y^{2}\right)$$
Let us write down the identical expression
$$- 6 x^{2} + \left(x 4 y - y^{2}\right) = - \frac{y^{2}}{3} + \left(- 6 x^{2} + 4 x y - \frac{2 y^{2}}{3}\right)$$
or
$$- 6 x^{2} + \left(x 4 y - y^{2}\right) = - \frac{y^{2}}{3} - \left(\sqrt{6} x - \frac{\sqrt{6} y}{3}\right)^{2}$$
$$- 6 x^{2} + 4 x y - y^{2}$$
