Hey, so I know how to do synthetic division if im giving the (x-number) but I don’t know how to do it without that (x-number) and im wondering how I get it.
(X-number) as in (x-1), (x-2), (x+1), etc
I attached an image to give an example of the problem I’m facing

...there isn't a problem. There's no instructions.
sterile ginkgo
It says factor fully, using your method of choice

So why all the stuff about synthetic division?
sterile ginkgo
i think to reduce the whole equation and once it's smaller i'll be able to factor it
stray peak
Okay, well, what's P(1)?
sterile ginkgo
the function right?
stray peak
...yes.
sterile ginkgo
do you mean to replace all the k's with 1s?
stray peak
...yes, that's generally how it works.
sterile ginkgo
okay, but why can't it be P(3) or P(2) where did 1 come from?
stray peak
...because just trust me.

i still don't quite understand, even if i replace k with 1 I'll still the get the same numbers what would I do with these numbers if I don't have a divisor for the polynomial?

...do you seriously not know how to evaluate a function at a point?
sterile ginkgo
no this is why i'm asking
stray peak
You replace all the ks with 1s. Then you do the math.
sterile ginkgo
do the math as in add all the numbers together which would equal zero
stray peak
Right.
sterile ginkgo
but how would this help me in getting the divisor for the synthetic division
