Factor x^3 + 3x^2 - x - 3

Factor x^3 + 3x^2 - x - 3

[spiritualmeli]

Where did you get the first x^2?! Or the x+3?! WTF

[lopezmoctezumamanuel]

But for rational zeros? I look for possible zeros and their factorization

[justinerainellobrera]

I came here because of the solutions of this,
(x^3 + 3x^2 - x - 3) divided by (x - k) with remainder -15

the answer is,
k= -4
k= (1+ i square root of 11) /2
k= (1- i square root of 11) /2

but what is the solution...

you cant expand the (x^2-1) because the exponent is on the inside of the bracket and does not apply to all the terms inside. It only effects the x

Wth the question you have written is wrong bro

sir plz tell me the factors of 3x³+x²+x
