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
$$m! + 12 = n^{2}$$
en
$$- n^{2} + \left(m! + 12\right) = 0$$
Es la ecuación de la forma
La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$n_{1} = \frac{\sqrt{D} - b}{2 a}$$
$$n_{2} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = -1$$
$$b = 0$$
$$c = m! + 12$$
, entonces
La ecuación tiene dos raíces.
o
$$n_{1} = - \frac{\sqrt{4 m! + 48}}{2}$$
$$n_{2} = \frac{\sqrt{4 m! + 48}}{2}$$
miembro izquierdo de la ecuación con el signo negativo.
La ecuación se convierte de
$$m! + 12 = n^{2}$$
en
$$- n^{2} + \left(m! + 12\right) = 0$$
Es la ecuación de la forma
a*n^2 + b*n + c = 0
La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$n_{1} = \frac{\sqrt{D} - b}{2 a}$$
$$n_{2} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = -1$$
$$b = 0$$
$$c = m! + 12$$
, entonces
D = b^2 - 4 * a * c =
(0)^2 - 4 * (-1) * (12 + factorial(m)) = 48 + 4*factorial(m)
La ecuación tiene dos raíces.
n1 = (-b + sqrt(D)) / (2*a)
n2 = (-b - sqrt(D)) / (2*a)
o
$$n_{1} = - \frac{\sqrt{4 m! + 48}}{2}$$
$$n_{2} = \frac{\sqrt{4 m! + 48}}{2}$$
Teorema de Cardano-Vieta
reescribamos la ecuación
$$m! + 12 = n^{2}$$
de
$$a n^{2} + b n + c = 0$$
como ecuación cuadrática reducida
$$n^{2} + \frac{b n}{a} + \frac{c}{a} = 0$$
$$n^{2} - m! - 12 = 0$$
$$n^{2} + n p + q = 0$$
donde
$$p = \frac{b}{a}$$
$$p = 0$$
$$q = \frac{c}{a}$$
$$q = - m! - 12$$
Fórmulas de Cardano-Vieta
$$n_{1} + n_{2} = - p$$
$$n_{1} n_{2} = q$$
$$n_{1} + n_{2} = 0$$
$$n_{1} n_{2} = - m! - 12$$
$$m! + 12 = n^{2}$$
de
$$a n^{2} + b n + c = 0$$
como ecuación cuadrática reducida
$$n^{2} + \frac{b n}{a} + \frac{c}{a} = 0$$
$$n^{2} - m! - 12 = 0$$
$$n^{2} + n p + q = 0$$
donde
$$p = \frac{b}{a}$$
$$p = 0$$
$$q = \frac{c}{a}$$
$$q = - m! - 12$$
Fórmulas de Cardano-Vieta
$$n_{1} + n_{2} = - p$$
$$n_{1} n_{2} = q$$
$$n_{1} + n_{2} = 0$$
$$n_{1} n_{2} = - m! - 12$$
