I need to create a polynomial whose real zeros are: -1, 2, 3, and 7 and whose degree is 4. Thanks!

With the given zeros we can say

%0D%0AP%28x%29=a%28x-%28-1%29%29%28x-2%29%28x-3%29%28x-7%29%0D%0A

%0D%0AP%28x%29=a%28x-%28-1%29%29%28x-2%29%28x-3%29%28x-7%29%0D%0A

where

is any nonzero real number

so if a=1

a=1

we get

P%28x%29=x%5E4-11+x%5E3%2B29+x%5E2-x-42%0D%0A

:)
