Answer:
p(x)=(x)(x-2)(x-4)
Step-by-step explanation:
One way to factor function p is by grouping.
p(x)=x^3-2x^2-4x^2+8x (Group the terms)
=(x^3-2x^2)+(-4x^2+8x) (Factor each group separately)
=x^2(x-2)-4x(x-2) (Factor x-2 from each term.)
=x(x-4)(x-2)

What is a polynomial function?
A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation.
Given polynomial function
[tex]p(x)=x^{3}-2x^{2} -4x^{2} +8x[/tex]
Group the terms
= [tex](x^{3} -2x^{2} )+(-4x^{2} +8x)[/tex]
Factor each group separately
= [tex]x^{2} (x-2)-4x(x-2)[/tex]
Factor [tex]x-2[/tex] from each term
= [tex](x^{2} -4x)(x-2)[/tex]
Factor [tex]x[/tex] from [tex]x^{2} -4x[/tex]
= [tex]x(x-4)(x-2)[/tex]
Factors of given polynomial function [tex]x(x-4)(x-2)[/tex].
