Find a polynomial function that has the given zeros. (There are many correct answers.)
−4, 6

If polynomial function vanishes at

x

=

a

, then

(

x

−

a

)

must be one of its factors.

Thus

(

x

)

,

(

x

−

−

√

6

)

and

(

x

−

4

+

√

6

)

are factors of the required polynomial.

The simplest polynomial that satisfies this is

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
