Answer 1

Respuesta:

Explicación paso a paso:

(x+1)(x+2)(x-3)=(x-2)(x+1)(x+1)1

(x^2+2x+x+2)(x-3)=(x-2)(x+1)^2

(x^2+3x+2)(x-3)=(x-2)(x+1)^2

x^3-3x^2+3x^2-9x+2x-6=(x-2)(x^2+2x+1)

x^3-9x+2x-6=x^3+2x^2+x-2x^2-4x-2

x^3-7x-6=x^3+x-4x-2

x^3-7x-6=x^3-3x-2

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

-4x = 4

x = 4 / - 4

x = - 1
