Answer 1

Reminder:
if you have a zero that's equal to -4, the root of the function can be written as (x+4)
the function should factor to those zeros.

your zeros are -4, -2, 1
or the roots,
(x+4)(x+2)(x-1)
so f(x)=x+4)(x+2)(x-1)
expand the parenthesis and re-write the function.

Answer 2

what would be the equation then?@SolomonZelman

Answer 3

can you expand (x+4)(x+2)(x-1) ?

Answer 4

one sec

Answer 5

I got x^3 5x^2+2x-8

Answer 6

oh, my bad, there are 4 roots, I forgot about (0,0) then i am not sure.

Answer 7

sorry, idk

Answer 8

so what will it be then??? @SolomonZelman

Answer 9

I don;t know, not good at math.

Answer 10

@Loser66

Answer 11

just put x in the front . it is \(x(x+4)(x+2)(x-1) \) then expand them

Answer 12

ok wait one sec

Answer 13

oh, yeah x, ty!

Answer 14

@Loser66 I got

Answer 15

x^4 +5x^3 + 2x^2 -8x

Answer 16

is it right???
