Ayuda a resolver por factorizacion por favor ?

Ayuda a resolver por factorizacion por favor . N2 - 6 - n x3 + 4x = 7x x2 + 6x + 8 = 0 5x2 + 10x4 = 0.

<img src="https://tex.z-dn.net/?f=%20n%5E%7B2%7D%20-n-6" /> + 2n = n

n - 3

n + 2 - 3n + 2n = - n

(n - 3)(n + 2)

[img = 10]

x + 4

x + 2

2x + 4x = 6x

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

x + 4 = 0 x + 2 = 0

x = - 4 x = - 2

CS = ( - 4 ; - 2).
