Evaluate each limit.
Only consider the highest power in the numerator and the denominator. If they are the same, remember to account for their coefficients.
For some limits, approaching
will lead to a different result than approaching . This is one of those cases. Explain.
Reduce the complex fraction to a more simplified version. Factor the denominator. Simplify. At this point, you should be able to substitute
into the expression and not get division by .
