there must me more to the question than just \[x=-2,1,4\]
OpenStudy (plasmataco):
u all gud?
OpenStudy (anonymous):
Oh yeah, sorry about that. Question is: Write a Polynomial function with the given zeros.
OpenStudy (anonymous):
No @Plasmataco I could use a hand if you don't mind
OpenStudy (plasmataco):
k

OpenStudy (plasmataco):
ok....
OpenStudy (plasmataco):
so u invert them
OpenStudy (plasmataco):
(X+2)(X-1)(X-4)
OpenStudy (anonymous):
ooh i see
the factors are going to be \(x+1,x-1,x-4\)
OpenStudy (plasmataco):
and then u multiply them all together

then multiply that mess out
OpenStudy (anonymous):
i would cheat so as not to make an algebra mistake
OpenStudy (plasmataco):
(X+1)(X-1)=\[X ^{2}-1\]
OpenStudy (plasmataco):
Wat.
OpenStudy (plasmataco):
do u need it in standard form or factor form

Standard would be best
OpenStudy (plasmataco):
k
OpenStudy (plasmataco):
this might take a minute
OpenStudy (anonymous):
I mean factor form is good as well. It doesn't matter
OpenStudy (plasmataco):
nah, i got u

OpenStudy (anonymous):
What steps did you take to get that? Just because I kinda have to write them down
OpenStudy (plasmataco):
ouch...
OpenStudy (plasmataco):
k.

k lel
OpenStudy (plasmataco):
(x^2-x-2)(x-4)=(x^2*x-x*x-2*x-4*x^2-4*x-4*-2
OpenStudy (plasmataco):
oh yeah, I messed up for the answer. It is X^3-5X^2-6X+8
OpenStudy (plasmataco):
anyways, My bed times coming up cause I'm in 8th grade so I don't want to rush u but u know.
OpenStudy (plasmataco):
