To find the greatest common factor (GCF) of 21x^2y and 63xy^2, you first identify the common factors of the coefficients (21 and 63), which is 21. Then, consider the variables x and y. Both terms have x and y as common variables, with the lowest power of x being 1 and the lowest power of y being 1. Thus, the GCF is 21xy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
