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!
