Question

factorización de 3X^2+2X-1=0​

Answer 1

Respuesta:

(3x-1)(x+1)

Explicación paso a paso:

$3x^{2} +2x - 1 =0\\a = 3 // b =2 // c =-1$

Formula general:

$x = \frac{-b+-\sqrt{b^{2} - 4ac} }{2a}$

$x = \frac{-2+-\sqrt{2^{2} - 4(3)(-1)} }{2(3)}$

$x = \frac{-2+-\sqrt{4 + 12} }{6}$

$x = \frac{-2+-\sqrt{16} }{6}$

$x = \frac{-2+-4}{6}$

Solución 1:

$x = \frac{-2+4 }{6} =\frac{2}{6} = \frac{1 }{3}$

x = 1/3

3x = 1

3x - 1 = 0

(3x-1)

Solución 2:

$x = \frac{-2-4 }{6} =\frac{-6}{6} = -1$

x = -1

x + 1 = 0

(x+1)
