Question

Write a polynomial function with the given zeros x=-1,-1,6

Answer 1

Hello from MrBillDoesMath!

Answer:

x^3 - 6 x^2 - x + 6

Discussion:

The polynomial is

(x-1) (x - (-1)) (x-6) =

(x-1)(x+1)(x-6) =                     => as (x-1)(x+1) = x^2 - 1

(x^2-1)(x-6) =    

x^2(x) - 6 x^2 - 1x + 6 =

x^3 - 6 x^2 - x + 6

Thank you,

MrB
