Hi how can i factor this limit?
Find the limit
Do you know the Rational Roots Theorem?
Given a polynomial:
If a rational root of this polynomial exists it will be of the form:
In this case we have:
So if there is a factor of this over the rational numbers it will be of the form:
So the possible rational factors of are:
You can try each of these and find that (x + 1) is the only linear rational factor.
