So in 33, we're trying to find out if there is a vertical asymptote or removable discontinuity at x equals negative 1.
00:09
So if you can factor, you should factor.
00:12
It's a good general rule of thumb of math.
00:17
So that factors difference of squares.
00:22
And then we see that this term cancels.
00:27
So it's gone from the bottom.
00:30
It does not correspond to a vertical asymptote.
00:32
It does correspond to a removable discontinuity, a hole.
00:39
So no vertical asymptote, yes, a removable discontinuity at x equals negative 1.
01:03
So here's the deal...
