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:
x1=Db2ax_{1} = \frac{\sqrt{D} - b}{2 a}
x2=Db2ax_{2} = \frac{- \sqrt{D} - b}{2 a}
donde D = b^2 - 4*a*c es el discriminante.
Como
a=ca = c
b=1b = 1
c=1c = 1
, entonces
D = b^2 - 4 * a * c = 

(1)^2 - 4 * (c) * (1) = 1 - 4*c

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

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

o
x1=14c12cx_{1} = \frac{\sqrt{1 - 4 c} - 1}{2 c}
x2=14c12cx_{2} = \frac{- \sqrt{1 - 4 c} - 1}{2 c}
Teorema de Cardano-Vieta
reescribamos la ecuación
(cx2+x)+1=0\left(c x^{2} + x\right) + 1 = 0
de
ax2+bx+c=0a x^{2} + b x + c = 0
como ecuación cuadrática reducida
x2+bxa+ca=0x^{2} + \frac{b x}{a} + \frac{c}{a} = 0
cx2+x+1c=0\frac{c x^{2} + x + 1}{c} = 0
px+q+x2=0p x + q + x^{2} = 0
donde
p=bap = \frac{b}{a}
p=1cp = \frac{1}{c}
q=caq = \frac{c}{a}
q=1cq = \frac{1}{c}
Fórmulas de Cardano-Vieta
x1+x2=px_{1} + x_{2} = - p
x1x2=qx_{1} x_{2} = q
x1+x2=1cx_{1} + x_{2} = - \frac{1}{c}
x1x2=1cx_{1} x_{2} = \frac{1}{c}
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
cx2+x+1=0c x^{2} + x + 1 = 0
Коэффициент при x равен
cc
entonces son posibles los casos para c :
c<0c < 0
c=0c = 0
Consideremos todos los casos con detalles:
Con
c<0c < 0
la ecuación será
x2+x+1=0- x^{2} + x + 1 = 0
su solución
x=1252x = \frac{1}{2} - \frac{\sqrt{5}}{2}
x=12+52x = \frac{1}{2} + \frac{\sqrt{5}}{2}
Con
c=0c = 0
la ecuación será
x+1=0x + 1 = 0
su solución
x=1x = -1
