Please see below.


Step 1, Find the zeros of the denominator.

Step 2 Test to see whether any of the zeros pf the denominator are also zeros of the numerator. For any zero of both, we have a common factor. Reduce the fraction and check the remaining zeros of the new denominator.

Step 3. For each remaining zero of the denominator, ther ts a vertical; asymptote at #x = # the zero.
