Question

x²+2x-8=0 factorizacion ​

Answer 1

Respuesta:

(x-2)(x+4)

Explicación paso a paso:

(x-2)(x+4)

(x)(x)=x^2

(x)(4)=4x

(-2)(x)= -2x

(-2)(4)= -8

x^2 + 4x - 2x - 8

x^2 + 2x - 8

Answer 2

Respuesta:

X = 2, -4 o' X1 = -4. X2 = 2

Explicación paso a paso:

$x {}^{2} + 4x - 2x - 8 = 0$

$x(x + 4) - 2(x + 4) = 0$

$(x + 4)(x - 2) = 0$

X + 4 =0

X + 4 - 4 = 0 - 4

X = 0 - 4

X = - 4

x - 2 = 0

x - 2 + 2 = 0 + 2

x = 0 + 2

x = 2

x = -4

x = 2
