\begin{gathered} \text{zeros:}-2,2,4 \\ \text{Degres:}3 \end{gathered}

Then,

From the given polynomial:

f(x)=(x+2)(x-2)(x-4)

Then,

\begin{gathered} f(x)=(x+2)(x-2)(x-4) \\ f(x)=(x^2-2x+2x-4)(x-4) \\ f(x)=(x^2-4)(x-4) \\ f(x)=x^3-4x^2-4x+16 \end{gathered}

Final answer:

Hence, the polynomial is shown below:

f(x)=x^3-4x^2-4x+16

Convert 26\%26%26, percent to a fraction in simplest form.

So 26/100 simplified is 13/50.
