Solución
Ha introducido

2 2 2 (x + 2) + y + (z - 1) = 9
$$\left(y^{2} + \left(x + 2\right)^{2}\right) + \left(z - 1\right)^{2} = 9$$
Solución detallada
Transportemos el miembro derecho de la ecuación al
miembro izquierdo de la ecuación con el signo negativo.
La ecuación se convierte de
$$\left(y^{2} + \left(x + 2\right)^{2}\right) + \left(z - 1\right)^{2} = 9$$
en
$$\left(\left(y^{2} + \left(x + 2\right)^{2}\right) + \left(z - 1\right)^{2}\right) - 9 = 0$$
Abramos la expresión en la ecuación
$$\left(\left(y^{2} + \left(x + 2\right)^{2}\right) + \left(z - 1\right)^{2}\right) - 9 = 0$$
Obtenemos la ecuación cuadrática
$$x^{2} + 4 x + y^{2} + z^{2} - 2 z - 4 = 0$$
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
$$a = 1$$
$$b = 4$$
$$c = y^{2} + z^{2} - 2 z - 4$$
, entonces
La ecuación tiene dos raíces.
o
$$x_{1} = \frac{\sqrt{- 4 y^{2} - 4 z^{2} + 8 z + 32}}{2} - 2$$
$$x_{2} = - \frac{\sqrt{- 4 y^{2} - 4 z^{2} + 8 z + 32}}{2} - 2$$
miembro izquierdo de la ecuación con el signo negativo.
La ecuación se convierte de
$$\left(y^{2} + \left(x + 2\right)^{2}\right) + \left(z - 1\right)^{2} = 9$$
en
$$\left(\left(y^{2} + \left(x + 2\right)^{2}\right) + \left(z - 1\right)^{2}\right) - 9 = 0$$
Abramos la expresión en la ecuación
$$\left(\left(y^{2} + \left(x + 2\right)^{2}\right) + \left(z - 1\right)^{2}\right) - 9 = 0$$
Obtenemos la ecuación cuadrática
$$x^{2} + 4 x + y^{2} + z^{2} - 2 z - 4 = 0$$
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
$$a = 1$$
$$b = 4$$
$$c = y^{2} + z^{2} - 2 z - 4$$
, entonces
D = b^2 - 4 * a * c =
(4)^2 - 4 * (1) * (-4 + y^2 + z^2 - 2*z) = 32 - 4*y^2 - 4*z^2 + 8*z
La ecuación tiene dos raíces.
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
o
$$x_{1} = \frac{\sqrt{- 4 y^{2} - 4 z^{2} + 8 z + 32}}{2} - 2$$
$$x_{2} = - \frac{\sqrt{- 4 y^{2} - 4 z^{2} + 8 z + 32}}{2} - 2$$
