Question

Write a polynomilal function in standard form with the given zeros.

1. x = -1, 3, 4

Answer 1

example: x=5, 6, -9.

this will become: (x-5)(x-6)(x+9)

got that?

Answer 2

so (+1)(-3)(-4)

Answer 3

you forgot the x :D

Answer 4

(x+1)(x-3)(x-4)

then multiply them together.

Answer 5

woops (x+1)(x-3)(x-4)

Answer 6

yeah this is the part where i get confused

Answer 7

use FOIL for the first two, then just simply multiply the other one.

Answer 8

(x+1)(x-3)(x-4)


USE FOIL METHOD HERE FIRST: (x+1)(x-3)

Answer 9

\[x^2 - 3x + 1x - 3\] ?

Answer 10

simplify it to : \(x^2-2x-2\).

Answer 11

then multiply that equation above to (x-4).

Answer 12

wait how'd you get 2?

Answer 13

x^2-3x+1x-3

notice that -3x and 1x have the same degree.

SO -3x+1x= -2x

Answer 14

Oh i meant the regular 2 with no x

Answer 15

now multiply this: \((x-4)(x^2-2x-3)\)

Answer 16

oh... that was a typo, sorry!

Answer 17

ohh okay, haha np

Answer 18

okay i get it now, thanks!

Answer 19

no problem!
