2 2 x + x*y - 2*y - x + y = 3
$$y + \left(- x + \left(- 2 y^{2} + \left(x^{2} + x y\right)\right)\right) = 3$$
Solución detallada
Transportemos el miembro derecho de la ecuación al
miembro izquierdo de la ecuación con el signo negativo.
La ecuación se convierte de
$$y + \left(- x + \left(- 2 y^{2} + \left(x^{2} + x y\right)\right)\right) = 3$$
en
$$\left(y + \left(- x + \left(- 2 y^{2} + \left(x^{2} + x y\right)\right)\right)\right) - 3 = 0$$
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
$$a = 1$$
$$b = y - 1$$
$$c = - 2 y^{2} + y - 3$$
, entonces
La ecuación tiene dos raíces.
o
$$x_{1} = - \frac{y}{2} + \frac{\sqrt{8 y^{2} - 4 y + \left(y - 1\right)^{2} + 12}}{2} + \frac{1}{2}$$
$$x_{2} = - \frac{y}{2} - \frac{\sqrt{8 y^{2} - 4 y + \left(y - 1\right)^{2} + 12}}{2} + \frac{1}{2}$$
miembro izquierdo de la ecuación con el signo negativo.
La ecuación se convierte de
$$y + \left(- x + \left(- 2 y^{2} + \left(x^{2} + x y\right)\right)\right) = 3$$
en
$$\left(y + \left(- x + \left(- 2 y^{2} + \left(x^{2} + x y\right)\right)\right)\right) - 3 = 0$$
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
$$a = 1$$
$$b = y - 1$$
$$c = - 2 y^{2} + y - 3$$
, entonces
D = b^2 - 4 * a * c =
(-1 + y)^2 - 4 * (1) * (-3 + y - 2*y^2) = 12 + (-1 + y)^2 - 4*y + 8*y^2
La ecuación tiene dos raíces.
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
o
$$x_{1} = - \frac{y}{2} + \frac{\sqrt{8 y^{2} - 4 y + \left(y - 1\right)^{2} + 12}}{2} + \frac{1}{2}$$
$$x_{2} = - \frac{y}{2} - \frac{\sqrt{8 y^{2} - 4 y + \left(y - 1\right)^{2} + 12}}{2} + \frac{1}{2}$$
Teorema de Cardano-Vieta
es ecuación cuadrática reducida
$$p x + q + x^{2} = 0$$
donde
$$p = \frac{b}{a}$$
$$p = y - 1$$
$$q = \frac{c}{a}$$

Fórmulas de Cardano-Vieta
$$x_{1} + x_{2} = - p$$
$$x_{1} x_{2} = q$$
$$x_{1} + x_{2} = 1 - y$$
$$x_{1} x_{2} = - 2 y^{2} + y - 3$$
