For the polynomial below, is a zero.

Express as a product of linear factors
since given the polynomial of degree , there will be three zeros and we can write it as:

since given is a zero, we have as one linear factor
....to find other two linear factors, use long division and divide by

-------(
|()
...............................subtract

so, we have
......now factor completely left side
first complete square
so, solve for :
if => => =�
=>solutions and
then, your polynomial is:
