me ayudaaaaaaaan porfassssaaaaaaahhh​

Answer 1

Respuesta:

X =  13/3

X =  11/3

Explicación paso a paso:

$3x^{2} - 4x = -1$

convertimos a ecuacion cuadratica del Tipo a$x^{2}$ + bx + c = 0

$3x^{2} - 4x + 1 = 0$

usaremos la formula general

X = -b ± $\frac{\sqrt{b^{2}-4ac } }{2a}$

remplazamos abc

X = -(-4) ± $\frac{\sqrt{(-4)^{2}-4(3)(1) } }{2(3)}$

resolvemos

X = 4 ± $\frac{\sqrt{16 - 12 } }{6}$

X = 4 ± $\frac{\sqrt{4} }{6}$

X = 4 + $\frac{2}{6}$  =  4 + 1/3  =  13/3

X = 4 - $\frac{2}{6}$   =  4 - 1/3   =  11/3
