Start with the given zeros

and

Get all terms to the left side in each case (ie subtract 1 from both sides in the first equation and add 8 to both sides in the second equation)

and

Now use the zero product property in reverse to join the factors.

FOIL and multiply

-------------------------------------------
Answer:

So the polynomial with zeros of and is

Notice how if we graph , we can see that the polynomial has roots of and

Graph of with roots of and
