Question

Write a polynomial function of least degree with integral coefficients that have the given zeros: -3, -5, 1

Answer 1

\[

(x-(-3))(x-(-5))(x-1) = (x+3)(x+5)(x-1)
\]

Answer 2

When you have a root \(r\) of a polynomial, you can factor it out as \(x-r\).

Answer 3

Now all you have to do is multiply out the terms.

Answer 4

So I would Foil that answer?

Answer 5

yeah
