#### Explanation:

Each zero (e.g.

Multiplicity corresponds to a repetition of that factor.

So in our example, the following polynomial fits the criteria:

#f(x) = (x-(-1))^3(x-0)^2(x-1)#

#color(white)(f(x)) = (x+1)^3x^2(x-1)#

#color(white)(f(x)) = x^2(x+1)^2(x-1)(x+1)#

#color(white)(f(x)) = x^2(x^2+2x+1)(x^2-1)#

#color(white)(f(x)) = x^2(x^4+2x^3-2x-1)#

#color(white)(f(x)) = x^6+2x^5-2x^3-x^2#
