To multiply , you should follow these steps:
- Factorize each polynomial if possible.
- Simplify the expression by canceling out common factors.
Starting with the given expression:
First, factorize the polynomials in the numerators and denominators:
- The polynomial can be factored into .
- The polynomial can be factored into .
Substitute these factorizations back into the original expression:
Next, simplify the expression by canceling out common factors. The factors and appear in both a numerator and a denominator, so they can be canceled out:
Thus, the simplified form of the given expression is:

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.
