a*x  + 2*x  + 2*a*x + a - 2 - x = 0
$$- x + \left(\left(a + \left(2 a x + \left(a x^{2} + 2 x^{2}\right)\right)\right) - 2\right) = 0$$
Solución detallada
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
False

$$b = 2 a - 1$$
$$c = a - 2$$
, entonces
D = b^2 - 4 * a * c = 

(-1 + 2*a)^2 - 4 * (2 + a) * (-2 + a) = (-1 + 2*a)^2 - (-2 + a)*(8 + 4*a)

La ecuación tiene dos raíces.
x1 = (-b + sqrt(D)) / (2*a)

x2 = (-b - sqrt(D)) / (2*a)

o
$$x_{1} = \frac{- 2 a + \sqrt{- \left(a - 2\right) \left(4 a + 8\right) + \left(2 a - 1\right)^{2}} + 1}{2 a + 4}$$
$$x_{2} = \frac{- 2 a - \sqrt{- \left(a - 2\right) \left(4 a + 8\right) + \left(2 a - 1\right)^{2}} + 1}{2 a + 4}$$
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x^{2} + 2 a x + a + 2 x^{2} - x - 2 = 0$$
Коэффициент при x равен
$$a + 2$$
entonces son posibles los casos para a :
$$a < -2$$
$$a = -2$$
Consideremos todos los casos con detalles:
Con
$$a < -2$$
la ecuación será
$$- x^{2} - 7 x - 5 = 0$$
su solución
$$x = - \frac{7}{2} - \frac{\sqrt{29}}{2}$$
$$x = - \frac{7}{2} + \frac{\sqrt{29}}{2}$$
Con
$$a = -2$$
la ecuación será
$$- 5 x - 4 = 0$$
su solución
$$x = - \frac{4}{5}$$
Teorema de Cardano-Vieta
reescribamos la ecuación
$$- x + \left(\left(a + \left(2 a x + \left(a x^{2} + 2 x^{2}\right)\right)\right) - 2\right) = 0$$
de
$$a x^{2} + b x + c = 0$$
como ecuación cuadrática reducida
$$x^{2} + \frac{b x}{a} + \frac{c}{a} = 0$$
$$\frac{a x^{2} + 2 a x + a + 2 x^{2} - x - 2}{a + 2} = 0$$
$$p x + q + x^{2} = 0$$
donde
$$p = \frac{b}{a}$$
$$p = \frac{2 a - 1}{a + 2}$$
$$q = \frac{c}{a}$$
$$q = \frac{a - 2}{a + 2}$$
Fórmulas de Cardano-Vieta
$$x_{1} + x_{2} = - p$$
$$x_{1} x_{2} = q$$
$$x_{1} + x_{2} = - \frac{2 a - 1}{a + 2}$$
$$x_{1} x_{2} = \frac{a - 2}{a + 2}$$
