We can factor the polynomial $8z^{16}-8$ using the rational root theorem, which guarantees that for a polynomial of the form $a_nx^n+a_{n-1}x^{n-1}+\dots+a_0$ there is a rational root of the form $\pm\frac{p}{q}$, where $p$ belongs to the divisors of the constant term $a_0$, and $q$ belongs to the divisors of the leading coefficient $a_n$. List all divisors $p$ of the constant term $a_0$, which equals $-8$

Learn how to solve common monomial factor problems step by step online. Factor the expression 8z^16-8. We can factor the polynomial 8z^{16}-8 using the rational root theorem, which guarantees that for a polynomial of the form a_nx^n+a_{n-1}x^{n-1}+\dots+a_0 there is a rational root of the form \pm\frac{p}{q}, where p belongs to the divisors of the constant term a_0, and q belongs to the divisors of the leading coefficient a_n. List all divisors p of the constant term a_0, which equals -8. Next, list all divisors of the leading coefficient a_n, which equals 8. The possible roots \pm\frac{p}{q} of the polynomial 8z^{16}-8 will then be. Trying all possible roots, we found that 1 is a root of the polynomial. When we evaluate it in the polynomial, it gives us 0 as a result.

Final answer to the problem

$\left(8z^{15}+8z^{14}+8z^{13}+8z^{12}+8z^{11}+8z^{10}+8z^{9}+8z^{8}+8z^{7}+8z^{6}+8z^{5}+8z^{4}+8z^{3}+8z^{2}+8z+8\right)\left(z-1\right)$
