00:01
So this is probably we're going to find the least common denominator.
00:03
Then we're going to put them together, or we're going to rewrite them using that least common denominator.
00:08
In order to find it, we do need to factor.
00:10
So we're to factor both of these denominators.
00:13
Since the a value is 1, we can do the quick factoring of guess and check.
00:16
So it will multiply us to 7 that adds to 8.
00:18
Well, that would be positive 7 and positive 1.
00:21
We would have p plus 7 times p plus 1.
00:24
So the one on the right, same idea.
00:26
We'll multiply us to negative 28 that adds to 3.
00:28
Well, that would be a positive 7, and a negative 7.
00:31
To 4, so p plus 7 times p minus 4.
00:34
Now we're ready to identify our least common denominator.
00:38
Let's start by identifying pieces that are in common.
00:40
Both of them contain a single p plus 7, so we're going to include that in our least common denominator, but only one time...
