#### Answer:

First start by putting the limiting values for the independent variable.

If the denominator becomes zero, then consider factoring the numerator and denominator and cancelling the common terms.

#### Explanation:

If both numerator and denominator come zero or infinity, try considering the L'Hospital rule.

You may repeat it as many times you like to get the desired limit.
