(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Polynomial question, am I correct?

1. The problem statement, all variables and given/known data

p(z) = z[tex]^{5}[/tex]-5z[tex]^{4}[/tex]+18z[tex]^{3}[/tex]-50z[tex]^{2}[/tex]+81z-45

Show that z - 1 is a factor of p(z)

2. Relevant equations

None

3. The attempt at a solution

Well since 1 is a root of p(z), then p(1) = 0

Then z - 1 is a factor?
