y  = 6*x - 4
$$y^{2} = 6 x - 4$$
Solución detallada
Transportemos el miembro derecho de la ecuación al
miembro izquierdo de la ecuación con el signo negativo.

La ecuación se convierte de
$$y^{2} = 6 x - 4$$
en
$$y^{2} + \left(4 - 6 x\right) = 0$$
Es la ecuación de la forma
a*y^2 + b*y + c = 0

La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$y_{1} = \frac{\sqrt{D} - b}{2 a}$$
$$y_{2} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = 1$$
$$b = 0$$
$$c = 4 - 6 x$$
, entonces
D = b^2 - 4 * a * c = 

(0)^2 - 4 * (1) * (4 - 6*x) = -16 + 24*x

La ecuación tiene dos raíces.
y1 = (-b + sqrt(D)) / (2*a)

y2 = (-b - sqrt(D)) / (2*a)

o
$$y_{1} = \frac{\sqrt{24 x - 16}}{2}$$
$$y_{2} = - \frac{\sqrt{24 x - 16}}{2}$$
Teorema de Cardano-Vieta
es ecuación cuadrática reducida
$$p y + q + y^{2} = 0$$
donde
$$p = \frac{b}{a}$$
$$p = 0$$
$$q = \frac{c}{a}$$
$$q = 4 - 6 x$$
Fórmulas de Cardano-Vieta
$$y_{1} + y_{2} = - p$$
$$y_{1} y_{2} = q$$
$$y_{1} + y_{2} = 0$$
$$y_{1} y_{2} = 4 - 6 x$$
