polynomial function help

[hollow grotto]

All i know is the
Roots are -3,2,6

[hollow grotto]

i got -20(x+3)(x-2)^2(x-6)

[vagrant cairn]

y=q(x-a)(x-b)(x-c), plug in the values for a b and c, and the point (-2, -32) and you should b able to get the answer.

That’s not working

[vagrant cairn]

Hold on, let me try.

[echo pelican]

Wait I’m dumb

I did it wrong, yes it works

Omg I’m so dumb, I wrote 4^2=4 bruh

[vagrant cairn]

It’s a quartic.

So it should be y=(x-a)(x-b)(x-c)(x-d)

Idk how I overlooked that

[hollow grotto]

Thats what i did, is q=-20?

i got a negative number which is weird because the function is positive

[vagrant cairn]

It’s a quartic

[vagrant cairn]

it definitely shouldn’t be -20

Btw even if it was a cubic it would be 1, not -20

[hollow grotto]

wait y=q(x+3)(x-2)^2(x-6)

is this a good start?

[vagrant cairn]

do y=q(x+3)(x-2)(x-6)(x-2)

That should get you the answer

[hollow grotto]

whats the value of d?

-2?

[hollow grotto]

y=1/4(x+3)(x-2)^2(x-6) ?
