I appreciate any help
suggest start by finding factors of the denominator
Shouldn't I divide first ?
3rd degree polynomial so 3 roots
yes, divide x64 by the denom
x^4* by the denom
notice the constant is -1 factors of -1 are +1 and -1 so (x+ 1) a factor
because the degree in the numer has to be smaller than that in the denom
