Respuesta :

x^3 + 7x^2 -6x -42

Take out common factors

x^2(x+7) -6(x+7)

group them together (combine the factors you pulled out, which are x^2 and -6 then group them. x+7 is repeated twice so that can be combined into one factor.

final factors:
(x^2-6) (x+7)

Answer:

= (x=7) x (x-6)

Step-by-step explanation:

x² = 7x - 6x - 42

Factor out x from expression

X squared x (x + 7) - 6x - 42

Factor out -6

X squared x (x + 7) - 6x (x+7)

Factor out x+7

(x+7) x (x-6)
