from "Product of Rational Expressions (variable a)"

Part 2

Which is true of this binomial factor?
A.
It must be a factor of the numerator of Z.
B.
It must be a factor of the denominator of Z.
C.
It must be a factor of the numerator of Z and a factor of the denominator of Z.
D.
It is possible that it is neither a factor of the numerator of Z nor a factor of the denominator of Z.
