Solución
Solución detallada
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
$$b = 3$$
$$c = -4$$
, entonces
La ecuación tiene dos raíces.
o
$$x_{1} = \frac{\sqrt{16 a + 9} - 3}{2 a}$$
$$x_{2} = \frac{- \sqrt{16 a + 9} - 3}{2 a}$$
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
True
$$b = 3$$
$$c = -4$$
, entonces
D = b^2 - 4 * a * c =
(3)^2 - 4 * (a) * (-4) = 9 + 16*a
La ecuación tiene dos raíces.
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
o
$$x_{1} = \frac{\sqrt{16 a + 9} - 3}{2 a}$$
$$x_{2} = \frac{- \sqrt{16 a + 9} - 3}{2 a}$$
