Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a^{2} x - 2 a = a^{2} + a x$$
Коэффициент при x равен
$$a^{2} - a$$
entonces son posibles los casos para a :
$$a < 0$$
$$a = 0$$
$$a > 0 \wedge a < 1$$
$$a = 1$$
Consideremos todos los casos con detalles:
Con
$$a < 0$$
la ecuación será
$$2 x + 1 = 0$$
su solución
$$x = - \frac{1}{2}$$
Con
$$a = 0$$
la ecuación será
$$0 = 0$$
su solución
cualquiera x
Con
$$a > 0 \wedge a < 1$$
la ecuación será
$$- \frac{x}{4} - \frac{5}{4} = 0$$
su solución
$$x = -5$$
Con
$$a = 1$$
la ecuación será
$$-3 = 0$$
su solución
no hay soluciones
