NettetProof: Clearly the product f(x)g(x) of two primitive polynomials has integer coefficients.Therefore, if it is not primitive, there must be a prime p which is a common divisor of all its coefficients. But p can not divide all the coefficients of either f(x) or g(x) (otherwise they would not be primitive).Let a r x r be the first term of f(x) not divisible by … Nettet26. mar. 2016 · you have to first do long polynomial division to transform the improper fraction into a sum of a polynomial (which sometimes will just be a number) and a …

This can be especially confusing when we have both exponentials and polynomials in the same expression, as in the previous checkpoint. In these cases, we should always double-check to make sure we’re using the right rules for the functions we’re integrating.
