To factor (x^2 + 7x + 8x + 56) by grouping, first, group the terms in pairs:

(x^2 + 7x) and (8x + 56)

Then, factor out the greatest common factor from each pair:

(x(x + 7)) and (8(x + 7))

Now, we can see that both terms have a common factor of ((x + 7)). Factor out this common factor:

((x + 7)(x + 8))

Therefore, the factored form of (x^2 + 7x + 8x + 56) is ((x + 7)(x + 8)).

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.
