Ok I have a probelm with find the polynoimal function which has these zeros:
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!
