Question

write the simplest polynomial function with the given zeros.

4i, 2, - 2

Answer 1

get ready to multiply

Answer 2

im ready!

Answer 3

Let's start with an example. Suppose the given zeros are 1 and 2. Then the corresponding polynomial is y = (x-1)*(x-2).
Which polynomial corresponds to the zeros 2, - 2?

Answer 4

Note that there IS multiplication in the above example.

Answer 5

(x-2)(x+2)

Answer 6

= x^2 - 4

Answer 7

yup
that is one factor

Answer 8

the other will be \((x+4i)(x-4i)=x^2+16\) multiply those two

Answer 9

you want me to check?
