Solución detallada
$$\sqrt{x - y^{2}} = 0$$
cambiamos
$$x - y^{2} = 0$$
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
$$a = -1$$
$$b = 0$$
$$c = x$$
, entonces
D = b^2 - 4 * a * c =
(0)^2 - 4 * (-1) * (x) = 4*x
La ecuación tiene dos raíces.
y1 = (-b + sqrt(D)) / (2*a)
y2 = (-b - sqrt(D)) / (2*a)
o
$$y_{1} = - \sqrt{x}$$
$$y_{2} = \sqrt{x}$$
