Ok I have a probelm with find the polynoimal function which has these zeros:(adsbygoogle = window.adsbygoogle || []).push({});

Zeros: 2, 4+sqrt.(5), 4-sqrt.(5)

Find the polynomial equation with the given zeros.

So far I know:

y=(x-2)(x-(4+sqrt.(5))(x-(4-sqrt.(5))

but is there any way I could make the factor (x-(4+sqrt.(5)) into a better one? For example:

Zeros: -2,-1,0,1,2

I did:

y=x(x^2-1)(x^2-4)

instead of y=x(x+2)(x+1)(x-1)(x-2)

Thanks!
