Solución
Solución detallada
Transportemos el miembro derecho de la ecuación al
miembro izquierdo de la ecuación con el signo negativo.
La ecuación se convierte de
$$\frac{y^{2}}{2} + y = c - \frac{x^{2}}{2}$$
en
$$\left(- c + \frac{x^{2}}{2}\right) + \left(\frac{y^{2}}{2} + y\right) = 0$$
Abramos la expresión en la ecuación
$$\left(- c + \frac{x^{2}}{2}\right) + \left(\frac{y^{2}}{2} + y\right) = 0$$
Obtenemos la ecuación cuadrática
$$- c + \frac{x^{2}}{2} + \frac{y^{2}}{2} + y = 0$$
Es la ecuación de la forma
La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$x_{1} = \frac{\sqrt{D} - b}{2 a}$$
$$x_{2} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = \frac{1}{2}$$
$$b = 0$$
$$c = - c + \frac{y^{2}}{2} + y$$
, entonces
La ecuación tiene dos raíces.
o
$$x_{1} = \sqrt{2 c - y^{2} - 2 y}$$
$$x_{2} = - \sqrt{2 c - y^{2} - 2 y}$$
miembro izquierdo de la ecuación con el signo negativo.
La ecuación se convierte de
$$\frac{y^{2}}{2} + y = c - \frac{x^{2}}{2}$$
en
$$\left(- c + \frac{x^{2}}{2}\right) + \left(\frac{y^{2}}{2} + y\right) = 0$$
Abramos la expresión en la ecuación
$$\left(- c + \frac{x^{2}}{2}\right) + \left(\frac{y^{2}}{2} + y\right) = 0$$
Obtenemos la ecuación cuadrática
$$- c + \frac{x^{2}}{2} + \frac{y^{2}}{2} + y = 0$$
Es la ecuación de la forma
a*x^2 + b*x + c = 0
La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$x_{1} = \frac{\sqrt{D} - b}{2 a}$$
$$x_{2} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = \frac{1}{2}$$
$$b = 0$$
$$c = - c + \frac{y^{2}}{2} + y$$
, entonces
D = b^2 - 4 * a * c =
(0)^2 - 4 * (1/2) * (y + y^2/2 - c) = -y^2 - 2*y + 2*c
La ecuación tiene dos raíces.
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
o
$$x_{1} = \sqrt{2 c - y^{2} - 2 y}$$
$$x_{2} = - \sqrt{2 c - y^{2} - 2 y}$$
Teorema de Cardano-Vieta
reescribamos la ecuación
