PLEASE HELP WILL FAN AND MEDAL


Write a polynomial function with the given zeros. Show all work.
a. x= -1, 0, 2
b. x= -2, 1, 4

Answer 1

Answer 2

ok... so if you know a zero

if x = -1 is a zero or root, then (x + 1) is a factor
x = 2 is zero or root then (x -2) is a factor
x = 0 is a zero then x is a factor

so the polynomial is

P(x) =x(x-2)(x+1)

distribute for the standard form

(b) use the same reasoning to identify the factors.

hope it helps

Answer 3

if x = -2 is a zero or root, then (x + 2) is a factor
x = 1 is zero or root then (x - 1) is a factor
x = 4 ? what do i do here?

Answer 8

if x = 4 is a zero then (x - 4) is a factor

so

P(x) = (x +2)(x-1)(x-4)

just distribute
