I remember dis, yey
so if a polynomial has roots
, 
, 
, it can be factored into
where a,b,c,d are constants
also, if a polynomial has rational coefients and a+bi is a root, then a-bi must also be a root
so our roots we need are
4,16, 1+9i and 1-9i
so assuming multiplity 1 (that means we have something like [/tex]f(x)=a(x-r_1)^1(x-r_2)^1(x-r_3)^1[/tex])
we get that your function is
which simplifies to
which expands to

Ok so our original fraction is:
To simplify this fraction, look for instances where the values on the top and bottom can be reduced:
For example, 36 over 6 is the same as 6 over 1, so we can simplify the fraction so it is:
We can also eliminate the denominator by dividing the nominator by x^9 so:
And that is the simplified answer of the fraction
Hope this helped
