For an assignment in my Algebra 2 class we have to find the rational zeros of the equation then write it in factored form.
I am a little lost and don't really get it
I have tried first getting the rational zeros and got
$1, 2, 4, 8$
Then using synthetic substition
$2$ | $1$ $-5$ $2$ $8$
____2 -6 -8____
From that i got
$1x^3$ $-3$ $-4$ and finally $0$
Then wrote it into a function
Which i don't know if it is correct, i also don't know what they mean by factor it
It would be helpful if you could show all you steps so i can actaully learn how to do it myself.
Thanks in advance!
