Question

write a polynomial equation with zeros -3,0,5

Answer 1

It will need to have x^3 as highest term.
Find the product (x+3)(x)(x-5), which is the polynomial having
the three zeros, -3, 0, 5.

Answer 2

so you have to solve (+3)(x)(x-5)?

Answer 3

You have to multiply the expression I posted to get the polynomial equations they produce, which is what the question seeks.

Start with (x+3)(x-5) =
then multiply that answer by x.

You can do it.

Answer 4

so its x^3-2x^2-15

Answer 5

Yes. Well done.
