Question 1014897
.
Find the zeros of the polynomial 

x^6-4x^5+4x^4
-------------------------------------


Factor {{{x^4}}} out of parentheses:


x^6-4x^5+4x^4 = {{{x^4*(x^2 - 4x + 4)}}}.


Next, {{{x^2 - 4x + 4}}} = {{{(x-2)^2}}}.


The roots of the original polynomial are x=0 of multiplicity 4 and x=2 of multiplicity 2.
