Quick help with a question? • Question Inside • Medal & Fan

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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 (plasmataco):

\[x ^{3}-5x^{2}-6x-8\]

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.

OpenStudy (anonymous):

Give me a short version lol

OpenStudy (plasmataco):

do u know foil?

OpenStudy (anonymous):

Yes

OpenStudy (plasmataco):

k.

OpenStudy (anonymous):

An even clearer description lol

OpenStudy (plasmataco):

A super huge foil

OpenStudy (plasmataco):

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):

lel

OpenStudy (anonymous):

8th and You take Alg 2? no way

OpenStudy (plasmataco):

sry

OpenStudy (plasmataco):

well, I'm asian if that helps explaining it.

OpenStudy (anonymous):

lol

OpenStudy (plasmataco):

I'm taking honors pre-calc next semester

OpenStudy (plasmataco):

but yeah, everything stereotypical

OpenStudy (plasmataco):

including karate taekwondoe, b+ ingrish, piano, violin, etc

OpenStudy (anonymous):

lol ok, have a goodnight.. You'll be on tmrw?

OpenStudy (plasmataco):

dunno, I'll try i guess

OpenStudy (plasmataco):

I got this weird Harvard class to take

OpenStudy (plasmataco):

and then a couple hours of piano and violen

OpenStudy (plasmataco):

and gotta do physics AP prep

OpenStudy (plasmataco):

And taekwondoe lessons.

OpenStudy (plasmataco):

I might poke around tomarrow but not for long

OpenStudy (plasmataco):

anyways, nice meeting u cya

OpenStudy (anonymous):

So you just like doing math for fun lol

OpenStudy (plasmataco):

good night!
