To simplify the expression (x^2 + 4x + 4)/(x^2 + 7x + 10) * (x^2 + 5x)/(x^2 + 6x + 8), we can factorize the numerator and denominator of each fraction and then cancel out any common factors.

First, let's factorize the numerator and denominator of each fraction:

Numerator 1: x^2 + 4x + 4 = (x + 2)(x + 2) Denominator 1: x^2 + 7x + 10 = (x + 5)(x + 2)

Numerator 2: x^2 + 5x = x(x + 5) Denominator 2: x^2 + 6x + 8 = (x + 4)(x + 2)

Now, we can cancel out the common factors:

(x + 2) from the numerator of the first fraction and the denominator of the second fraction.

After canceling out the common factors, the expression simplifies to:

(x + 2)/(x + 5) * x/(x + 4)

Therefore, the simplified expression is (x + 2)/(x + 5) * x/(x + 4).

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.
