# How do you divide #\frac { 3k ^ { 2} - 2k - 1} { 3k ^ { 2} + 10k + 7} \div \frac { 9k ^ { 2} - 1} { 3k ^ { 2} + 4k - 7}#?

To divide fractions, multiply by the 1st by the reciprocal of the 2nd.

Factor both numerators and denominators.

Cancel factors found in both numerator and denominator.

Multiply the remaining factors straight across.

The numerator can be rewritten as th square of the binomial.

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.
