To find the least common multiple (LCM) for the expressions 2r+2, r^2+r, and r+1, we need to factorize each expression and then determine the highest power of each factor that appears in any of the expressions.

The factorization of 2r+2 is 2(r+1), the factorization of r^2+r is r(r+1), and the factorization of r+1 is (r+1).

Now, we consider the highest power of each factor:

- The highest power of 2 is 1,
- The highest power of r is 1,
- The highest power of (r+1) is 1.

Therefore, the LCM of 2r+2, r^2+r, and r+1 is 2(r+1)(r).

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.
